Can somebody help me out.please?

really try and sit him down and tell him you love him and ask him whats wrong. if he over reacts just stay calm and don't get upset. maybe have one of his friends with you and confront him again. If he blames you for something you haven't done and keeps on being unreasonable maybe leave him alone for a while and see if he changes. if he keeps it up tell him you don't have to be around his yelling and give your feelings straight to him. honesty is best. if things don't change after a lot of work to try and fix things it might be time to leave him. but until it reaches that point stick by him and show you love him no matter what.
