Am I wrong?

My boyfriend and I are long distance. We were planning to see each other in two weeks but his friend is going home after being away at college for a month. My boyfriend wants to see his friend and not see me. We see each other twice a month if we're lucky. I'm upset and hung up from him on FaceTime when he mocked me for being upset. Now he's ignoring me when I try to talk it out. What should I do and am I wrong for being upset?
