I'm so sorry. That was so uncalled for. You shouldn't have to put up with this. I wouldn't write him a note. He needs to appoligze to you. You did nothing wrong. To be honest with you, if that would have been me I would have slammed the phone down on him. I'm having some ups and downs in my relationship right now, and when my man starts acting like a fool, I have no problem letting him know how I feel. Matter of fact, when he starts running his mouth on the phone, I just hang up on him. Sometimes we need to be a little mean to get the point accross.
I would tell him that he needs to be supportive of you. I would also tell him that your not going to put up with him disrespecting you like that.
