How should I handle a friend who is judgemental and insensitive?

For the past 7 years I have been friends with a guy I met in Michigan. I have noticed that for the first 3–4 years he was nice, understanding and helpful when I called him with a problem and he called me a lot also. He would come and visit me in NY several times a year and on occasion has given me gifts and lent me money when I was in a bind. Recently I have noticed a change in his attitude towards me. He seems critical of me and when I mention to him about some plans or ideas I might have that he doesn’t agree with he will critisize me, sometimes going as far as to make hurtful comments about my intelligence or question my judgement. This was the case yesterday when I called him and mentioned to him that I had plans to go to the Halloween Parade in the Village (why did I do that?). He asked me why I was going and said that it was basically sad that when I’m bored that I’m willing to do anything, etc., etc. Finally I got fed up and told him to call me when he actually wanted to talk and not critisize and then I hung up on him. This man seems so miserable at times and I suspect that this is why he never had a girlfriend (not ONE since I have known him!). Should I call and apologize to him for hanging up on him or should I wait for him to call me? Did I over react?
