Well, I'm not usually the type to put my feelings out like this but here goes. Just a side note ladies, if your gut is telling you something BELIEVE IT. I should've known something was up when he was still BEST friends with a girl who he's liked and she's liked him before. They've been on a date in the past but I'm not the type of girlfriend to be controlling and limit his friends. He bought me a promise ring, he told me he would never treat me like how guys have in the past, he assured me there was nothing to worry about and he doesn't have feelings for her. and I believed him. We were about to move in together, we were talking about getting married and starting a family. Then he goes on vacation with his girl best friend and has sex with her. I never would've imagined this would happen to me but before i even found out i just KNEW. in my stomach I just had this disgusting feeling that something happened. Surprisingly, when I found out I didn't yell or scream or threaten him or her (lol). I just told him I would pray for him and I hope he finds happiness and continues to follows God's path for him. So, that's it. He had sex with his best friend and I'm trying to figure out why I wasn't good enough for him. Moral of the story is, trust your gut.
