At my wits end! Am I doing the right thing here?

Thank you so much for your input Rere. I'm fairly confident that since I wrote this she has stopped talking to him, but then again he could have just found better ways to hide it. I'm a good detective so if I sense something is wrong, I usually find out what it is. Since I've had no evidence to suspect anything maybe she finally has moved on.

I know she's very manipulative, to get us both to believe she is a strict lesbian with NO interest in men, and then to turn around and flaunt her feelings at him to make him think about her like that, it's a mind game. A lot of women do this and I KNOW how the game works. My boyfriend may just be that blind to think that friends are friends (he is more logic than emotion), and by me over-reacting to what I have every right to react to, he might just be "rebelling" my authority which he has admitted to doing before. I hope that's the case and he doesn't have any real feelings for this girl.

But on that note, if she does come back into our lives and I find out about it one more time, I'm going to change things around. If he does care about me, which I know he does, this petty texting nightmare will end one way or another. It's immature at this point. I don't want to leave him but I would take a few days and maybe stay at my mom's house or something until he can figure out what is important to him. The impact on me leaving would be much more effective than if I asked him to leave the way our living situation is. And if THAT doesn't work, I would have to really think about things.

Thanks again for your advice .
