That's probably his way of coping with it. A breakup involves a lot of emotions...it really is a lot to deal with. It's easier to blame other people. I kind of did something similar with my girlfriend when we broke up after 6 years...although I didn't tell other people or anything. That's just low emotional maturity/intelligence....it has nothing to do with age. I mentioned the way I felt and she straightened me out real quick...it was pretty much the same situation that you described. I'm not sure why I tried to blame her for it other than the fact that it was naturally the easiest way to deal with it. It was all subconscious too. I doubt that he realizes that he is being such a jackass just because it's a lot of stuff to keep in perspective...it really is a huge loss to lose someone. (The only example I could think of is if someone went into a casino and blew a lot of money...they might blame it on luck, the casino, other players, anything but themselves. I suppose it might have a little to do with ego.) You could talk to him about it if you haven't already, but whether he'll accept what you're telling him...I have no idea. He seems pretty stubborn and to have convinced himself that it was all your fault. At least if you try to talk to him, then you will know that you've done everything you can...

So I can't remember whether it's emotional maturity or emotional intelligence that he's lacking in...I think in his case, it's a little bit of both. Either way, give yourself a gentle kick in the ass. Sorry if all of that doesn't make sense... Gotta go to work. Good luck with things...time will help.
