Hi there, I have a friend I've known for a number of years. He has developed behaviour which I find challenging. As an example, the other night, when he was drunk, he sent over over 80 messages, some of which involved video messages which were about a minute long each. A lot of of it was incoherent, but he repeatedly asked if we were friends. He is an incredibly physically strong individual and there is a strong undercurrent of violence if I don't agree with what he says (as well as constant passive aggressiveness). The next day, not really thinking much of what happened the night before, I asked if he wanted to spend some time together and was partaking in events I know he likes. He completely ignored me and I know he seen the texts. What is the underlying issue here and how can it be resolved?
