Ladies has this happened to u?

My man and I have had some serious trust issues. I have been faithful to him but, he has cheated on me several times n still is. I am nine mos pregnant. The problem is that if any males call me on the phone he gets upset. One day a friend called me to wish me a merry x mas but, he called me "baby" several times. My boyfriend was sitting next to me at the time. I didn't recognize the number and I answered it thinkin it was one of my kids. He was very upset and I was upset because this dude called me at 12:00am at night. I haven't talked to this guy in a while. We used to have a ual relationship that didn't work out. So, we chit chat off and on but, nothin more. The situation mad me so mad that I called the guy on the phone and beg him to talk to my boyfriend and he said he would but, my boyfriend wouldn't speak to him. Was I wrong too be upset? Was it wrong for my boyfriend to be upset? Should I have called the guy back? What do you think?
