<human>: My boyfriend of three years threatens to break up with me suddenly yesterday via text if I ever talk, see, or do anything at all without telling him with a male friend of mine that he "doesn't trust" because once when we were all out together, this friend--my boyfriend thinks--tried to make him jealous by bringing up our texts or a party my boyfriend didn't go to with us. 

This male friend is not a close friend of mine, but he is someone I respect, and we work in the same field, and, also, went to the same college. We have a lot of mutual friends, too. I don't want to be his best friend, but I feel it's not fair for my boyfriend to threaten to end our relationship if I ever talk to him again simply because he thinks this friend has the wrong intentions--I mean, the trust should be in me, anyway? 

I guess I could understand him asking us not to hang out, but not the never texting, talking again. 

Is this normal? How do I deal with this? He has a bad temper.

Could you distill the essence of the text into 1-3 sentences?
