Stop bitching and being so paranoid.... I'm sure he's not cheating on you. You guys have just been dating for a really long time....Things are probably changing.
Um. Well, he's probably comfortable with you. He doesn't think he needs to try so hard because you're right there in his arms no matter what. Don't worry about it.
So you are freaking out because he talks to you for a few hours less during the day now(that's just my guess because I really don't understand what you are saying)? You should calm down, and not be so paraniod.
