I started seeing this girl a bit older than me. I’m 29 and she’s 32. She’s cute, tall, feminine and blonde, just my type. We hit it off super well, I’ve never clicked with a girl like this one. We would literally laugh the whole time we were together. One time she told me about a guy she matched with on tinder before she met me. This guy was a paramedic and he happened to help her once when she fainted. They never went out or anything she says. Anyway, I noticed that he still followed her on insta. So I decided to be a complete fucking psycho and got a text app number and messaged her as if I was the paramedic guy. She went along and never mentioned anything about seeing someone exclusively (me). She then thought I was pranking her (we would prank call people together lol) and asked me “are you pranking me right now?” I said no. She then was like “oh remember that paramedic guy I told you about? He texted me asking me out” and I said “what did you say?” Knowing that she was down to meet up to go “for a walk”. She was like “I was trying to be polite” so I then told her that I would never tell her what to do but to me she was keeping her options open and she could chose whatever. She was like “are you upset? Do you want me to tell him I’m seeing someone?” I told her she didn’t need to. Anyway, I pushed it even more and messaged her as the “paramedic “ to hangout at his place to get a drink. And this is when she said yes to that. She then sent me a screenshot of her telling him she’s seeing someone but the bitch deleted a previous message she had sent him. So she’s lying to my fucking face as I am the guy texting her as the paramedic! She was like “I’m not interested in him, I really like you blah blah”. So I messaged again as the paramedic and I asked her “is it serious? We can still go for that walk ;)” and she replied “well we’re exclusive but I doubt it’s serious, I’m down for a walk!”. Anyway, I was really upset, this girl I really liked but knowing that she was down to meet with another guy when we were exclusive and she was even down to go to his place for a drink really hurt my feelings. The next day I broke up with her but never brought up the fact that it was me this whole time. I said that the reasons why I was breaking up was that I wasn’t ready to be in an exclusive relationship with anyone right now. she has been texting me and calling me and I just blocked her. Her friend called me and said she’s “a mess” and heartbroken. Anyway, I know what I did is pretty insecure and psycho but I had a feeling she was not loyal and I did this to myself but it helped me dodge a bullet.
