Wtf who does that ?

So lately my BF has been acting stupid, like annoyed mean stupid then he says he thinks I'm trying to change him, I finally tell him you know that good luck with everything & we should prob b friends & that he needs to tell me a answer & so I asked if he wanted to be with me a yes or no question & he texts back saying he's helping his friend with something, then he calls me krazy because I told him good luck in life & etc ( we've been dating for 5 years ) so now he's not talking to me or atleast texting me because I keep mentioning breaking up & not being together.  Why is he dodging the topic ? And me ?
