m sorry if this is a lengthy long post but I need a third party opinion on this.(NAMES of people ARE CHANGED).

I am 24 and live and work on Long Island My now Ex-GF is 21 year old Senior who goes to school in SUNY ALBANY.

Back story: My GF and I have known each other for many years our families are very close with each other. She and I have been hooking up on and Off and having sex for the past few years and have always liked each other. We didn’t date at first because she was still in high school and I was in college plus the age difference. I never loved anyone like this girl and couldn’t believe I couldn't like someone so much. Our official relationship began over the summer near the end of July. We rarely fought and had great sex and our families were very happy we were finally together. We’ve talked for many years about getting married and having kids.

However, there were some red flags that I ignored early on because I was in such love with her.She constantly talked about her ex-boyfriends(Matt and Garrick) she went to school with and it kinda annoyed me. She was very controlling and made me not use social media such as Instagram and delete all girls even friends off my Snapchat. She made me also stop hanging out and talking with one of my best friends who was a girl who was basically my sister. I agreed to all this because I loved her and was under her spell. While I would post her on my social media such as facebook and Instagram. She did not put up a single post of me. I asked her why she's like i'm gonna wait to the school semi-formal to post you and no one has to know my business. She also is going through lots of difficulty with her family. Her father used to be a major lawyer but now is a struggling drug addict in and out of jail. Her mother is struggling to make ends meat to send her and her sister to school and pay her mortgage. I know this a bad situation but she would use it against me to get her way always with things.

When she left for school in late August, I felt everything was fine with our relationship. We shared each other locations so I know where she was. She is president of her sorority and would go to lots of fraternity parties and mixers on weekends. Most nights her location showed she made it back home. Other nights she would sleep downtown were the parties where. I bought up my concern to her once. She said she slept at her roommates cousins Johnnies house. I joked saying did You sleep on the couch and she got mad at me saying she needed space for the rest of the day. I didn’t ask her again when she slept downtown because I didn’t wanna anger her more. Another night she posted a Snapchat story of her kissing a guy on the cheek. This upset me I told her to take it down. She told me she wanted space again and called me controlling. One night I was facetiming her late at night and one of her ex-boyfriends Matt hits her up to have sex and come over. I tell her to tell him she is dating me and to tell him to get lost. She's like I don't wanna be that girl who tells everyone I have a boyfriend and she told me not to worry shes done with him. Later one that night I check her location because I had my suspicions and she was not at her apartment. I checked she was at a upper class-man and grad student housing complex. I then call her and she didn't answer and she freaked out on me. She made up the excuse she was visiting her little sister who was having an anxiety attack and didn't wanna be at school . But I also had her sisters location on snap maps and she was at her freshman dorm .35 miles away when I calculated the distance on google maps. and Told me her ex boyfriend Matt lived at another student housing complex on the other side of campus and I was acting crazy and didn't trust her. She wanted space from me for the next 3 days and didnt start talking to me again until I got her sister from the train on Long Island and took her home.

My girlfriend came home towards the end of September for her sisters boyfriends father party and it was clear going to back to school changed her alot. She felt like she was better and cooler than me in some way and was acting suspicious at the party. she went upstairs at one point and saw her taking selfies in the mirror. I grab her phone and saw that on her snapchat she was frequently sending snaps to this guy George who I knew she had a thing with. She made up the excuse that he was gay and she didn't speak to me for the rest of the party. We had sex later on that night and she assured to me we were exclusive and I had nothing to worry about.

Around mid October I haven’t seen her in over almost month and asked if I could visit her. She said no she didn’t want me invading her life up there. Also she gave some B.S excuse that I probably didn't want her to visit me when I was in undergrad. I should’ve broke up with her then but didn’t because I loved her for so long and was going to see her on thanksgiving. And she said she was going to let me come up to formal at the end of the semester.(UPDATE: ENDS UP GOING TO FORMAL in DEC WITH ANOTHER GUY IN THE DRESS I BOUGHT HER LOL!!!) At the beginning of November her sister who goes to the same school. Spoke to me about not liking school at Albany and she didn’t wanna go to date night later. I asked if her sister was going and she said no my GF(her sister) wasn't gonna be there.

Later on that I got a Snapchat from my GF in a dress and make up. I asked her why she was all dressed up and she said to me don’t worry. I asked her if she was going to date night and she said it was a first date themed party. The next day she says she appreciate everything I do for her but wanted to take things slow with me. Her excuse was she need to focus on school work. I asked if we were still exclusive but she said I shouldn’t worry. She gave some B.S excuse that she wants to get back with me and there is no time frame when we get back together.

I lost my mind because I felt like I did and sacrificed so much for her. The next steps I took were excessive but led me to find she was cheating on me. I DMed her ex boyfriend Garrick from school on instagram on a whim. I did this because I had my suspicions. He told she didn’t say ever she was dating me and they had sex a few times together during the semester. Aslo during the summer she went over his house every Thursday while she was suppose to be at work.( I didn't know because I worked in the city in the summer during the week) While she was at his house he asked her about me and said I was just her family friend that had a crush on her but she had no feeling for me. He said when he dated her she cheated on him a bunch. He was able to prove it with a screenshot recording of her texting him to come over on our anniversary to come over at 3am and have sex. He said he also saw her with other guys walking home some nights. He also said they she has multiple guys in every frat there that she fucks. Aslo that her other ex boyfriend Matt lived at the housing complex I saw her on her location that night not the other one she told me and he saw her car parked there multiple times. I also can't believe Her little sister was in on the lies too but I found out she was also cheated on her boyfriend from back home too. Aslo when my girlfriend dated Garrick she cheated on him with the guy George she told me was gay. When I finally confronted her about it and showed her the texts she sent Garrick with the dates and times showing her number. She went crazy and denied everything saying now there was 0 chance of us getting back together in the future and how dare I reach out to Garrick.

When her mom called me I told her everything about her daughter cheating on me she didn’t believe it. She wanted us to meet over the winter break and talk things out and be friends for now because our families are very close. I’m just very hurt because I never loved anyone like her for so long. I still have some feelings for her because I loved her for many years. Also i'm not gonna lie she is very physically attractive and the sex was amazing(usually it is with the crazy ones lol) I dont think ill ever get and one better than her. But all my friends and close family say she is no good and I must cut her out of my life for good.

tl;dr: Girlfriend cheated on me while at school and broke up with me I feel so hurt and confused about what happened. I don't know why but I am still obsessed with her and can't move on.
