Some odd attitudes of my boyfriend.

I have 6 months left for my marriage with this guy. But he has certain attitudes that i have felt. He misinterprets statements a lot, tells everything to his Mom, he fumbles sometimes. When i am talking about some issue he is looking somewhere else, when i say something he is silent and looking cold.. then answers sometimes later. On road or street he feels like he is numb and cannot decide what to do. Also he doesn't make eye contact suppose i am talking to him looking at him, he looks and responses looking at my ears. When he us angry he doesn't know what he is saying and loses control and doesn't let anyone else talk. Plus he is suspicious. And suppose i am talking and there is some sound suddenly he says who is there? Who is coming? etc... i have been with this guy for 7 months.. and these are the things i am finding out.. Please suggest me what to do now i am very much tensed.. These are some clear signs..
