My (ex)girlfriend and I seemed to be having a pretty good time about 8 months into our relationship, but it started slowly going downhill around mid-summer. In July we went to Vegas and had a BLAST. It was so much fun and it all just seemed perfect.

For some reason shortly after returning from the vacation our sex pace slowed significantly. It became a chore to have sex with her, there always seemed to be some sort of excuse from her and it took convincing on my end to get in her pants. During this time she began talking about a male coworker friend of hers a lot and she kept trying to schedule events where the three of us would hang out, or would try to start 3 way convos through phone. It seemed odd, but I guess that's more of a side note.

About three weeks ago it became impossible to get her to visit me and do our usually hanging out.. I live 30 minutes away from her, but its never been an issue. She used to try to hang out with me all the time and now I was lucky to have her over twice in a week. She kept making excuses and pretty much stopped coming to see me. I begin complaining about this.

Last Monday (21st) she tells me that some coworker friends are in town from California for business and the group included one who "used" to be infatuated with her. She insisted on being alone that Tuesday night and when I texted her, she seemed drunk (not normal even for a weekend, let alone a Tuesday), putting together incoherent sentences and misspelling simple words. She denied drinking. Then she insisted on staying with me on Wednesday. We had a good night and slept together like normal. No sex, of course.

Then comes yesterday. D Day. She went out with this group of coworkers, which I was fine with. I can quickly tell once again that she'd been drinking. Same thing as last time. Eventually around 10:30 she stopped texting me, even though she was still out with her friends. I texted a final goodnight at 11:30 or so with no reply back. I wake up, no text, no nothing. Odd. I go to work (she's a coworker) and not only isn't she in on time, she's over an hour late. Now I'm calling and texting her trying to see if she's okay. No answer. Worried that she may have gotten hurt or something, I drive to her house and knock. No answer. Knock again. No answer. Pound on the door. No answer. Then I use her extra key to unlock the door and it's chain locked (very odd, she never does). Finally I call to her and she comes to the door.

I'm upset, I go on about being worried sick and how rude it was to ignore me. She grabbed a hold of me and pulled me down to the bed in a vice grip of a hug, apologizing. Then she tells me what happened and starts with talking about going for a jog with 2 guys, one of them is the infatuated one. I get upset because she cancelled zumba to go with them, something I could NEVER convince her to do no matter what the day was. For some reason that was the final straw and I stormed out.

Later in conversation I'm telling her everything. How much her distance is bothering me and how I feel tossed aside. Guess what she does? SHE TURNS ON ME!!! She begins lecturing me about how I don't trust her and I keep trying to reemphasize my original point, feeling neglected, but she won't have it. She kept flipping the blame on me even though I was clearly the victim here. It all ends that night with her telling me we need time apart, to grow, to fix ourselves, and maybe come back together again. I told her FUCK no. I'm not playing that game. We either address our problems and move forward as a couple or we're finished, forever. She got pissed at me and started screaming uncontrollable over the phone. Then hung up.

I get a text saying "we're done."

Now... Can someone break this down for me? What in the ever blue fuck just happened? How did I lose my girlfriend so suddenly when things seemed to be going perfect???

HOW?! I'm so freaking confused.. I just want to know for future reference, so I don't fall into the same potential trap again.

Thanks.
