Yeah, it sounds like has issues he needs to work on. It’s possible that this is just how he is. His culture may have something to do with it as well, but it’s said that 6 to 7 months is about the time that the “honeymoon phase” in a relationship starts to wear off (although sometimes it lasts longer than that), and that’s when you really start to see people’s true colors.

So, I think the decision now lies on you and what you’re willing to put up with. If it were me, I would have a serious talk with him about his behavior and let him know it’s unacceptable. If he cannot stop accusing you of cheating and all of these other things, then you should either break up or he should seek counseling if he’s willing and wants to change. But that will only work if he WANTS to do it. He may be able to change on his own without counseling if he actively works to change his behavior, but, again, he’d have to want to. Otherwise, if he is unwilling to see how his behavior is affecting you and unwilling to change, I would move on and find someone who would treat you better, because I can imagine it would be hard be stay happy in a relationship where this kind of treatment is going on.
