I know he is cheating, but I dont have the strength to leave:( UPDATE*
So I confronted him, even showed his the status and he said he never wrote that, and that if he was talking about someone that the person would have liked or commented on it. BS!! He didn't write it, what kind of excuse is that?? I told him that we can't work through it if he doesn't admit and he still swore he isn't pong anything. He also said if he was cheating he wouldn't be here he would have his own place or stay with his friend B****. And that we wouldn't be getting a house in the next few weeks, we wouldn't be going out together on date nights, he wouldn't keep telling me to work at his job, and a whole bunch of other excuses. He told me that there is a big difference between me and his ex. And just because we did what we did doesn't mean he's doing with anyone else, because he did that because this is where he wanted to be but I don't know, I think he's lying. And I mentioned how his phone goes off late and he's so secretive and he said his friend randomly txts him stupid shit and to ask him and that he's just a private person. It's hard because I'm not sure if he is doing anything and if it is even sexual. I got a job BUT I don't start until September:/ what now??
