Ok, so long story short I caught a girl that I really like with another guy at her place. She knew I was coming to pick her up, and I get there and shortly after another car pulls up with the other guy. He's staring me down and I'm like 'Are you her boyfriend?' He looks at her, she won't answer. She's redfaced and on the verge of crying. I asked her if she was coming with me or him or what? She just stands there for a minute and says we can both come in if we want to. I tell her I have to be somewhere in an hour and give her a hug and look her right in the eye and tell her flatly, Goodbye. I leave and have pretty much ignored any of her texts and calls for about a week. We both work weekends at the same place, so it was inevitable that I'd see her again. Yesterday at work I texted her and told her I wanted to talk to her on her break with the intention of telling her I was moving on, and she could date the other guy. I don't wanna be two timed, but best of luck, hope it works out etc. She doesn't answer and later I pass by an office room and she's in there head down crying, I come in put my hand on her back, and kinda reassuringly say hello. She goes on to tell me that she's told the other guy to buzz off and that she wants me. Problem is, I dont' believe her, why should I? But I caved and got to talking to her instead of just ending it right there. Simply put I don't trust her anymore, and wanna take the high road here.. should I just end this? By the way, we aren't and never have been exclusive with each other, but she had told me on several occasions that I was the only guy in her life. So that's why I feel betrayed.
