Don't know why your guy went off on you; you'd have to ask him. That would be a good way to learn what sorts of things you did want to share with him and what not to? If you told him to get attention/reassurance and he behaved that way because he was super pissed at the friend for saying that, then that would be one thing. If he was pissed that you were even thinking/caring about such a "friend" and what he said, that would be another.

I'd work on my self esteem so others would not be likely to say that to me and so I did not have any "friends" who would even think of saying it in the first place.
