Did He Blow Me Off or Am I Being Selfish?

My fiance told me that he had plans with his friends today. We cut running errands short and got home about 1pm because he said they'd be calling any minute to tell him what the plan was. At 9pm, he still hadn't heard anything so I suggested he and I go catch a showing of a movie we had been wanting to see for quite awhile. He told me, "I'll go with you if you kiss me" so I kissed him. As I was getting ready to go to the movie, he got a call from his friends and told me he was going to hang out with them. I tried not to be upset but it did kind of bother me. He realized I was upset and asked me why. When I told him I thought he and I had plans, he told me no and that he was only kidding when he had said that. That hurt me even more.

Earlier today, he took me out to lunch. It was a new place and the bill was more than we had both anticipated so I offered to split it with him. He told me not to worry about it and said he wanted it to be his treat. Well tonight, this whole thing about the movie turned into a fight and he said, "You want to just go so you can throw away more money on trivial things while I am forced to buy you an expensive meal." I had no idea where this was coming from. I told him I wasn't angry I was just sad. I really thought when he hadn't heard from his friends for hours on end that their plans were canceled.

He then accused me of not letting him hang out with his friends without my permission. When I started crying, he asked me if he needed to take me in for an appointment with my psychiatrist to up my meds - talk about a low blow!

I am not upset that he had plans I am upset that when his plans seemed to be canceled, he made plans with me and then blew me off. He told me I was being so selfish and insane about all of this and it really hurt my feelings even more.

Am I being selfish? What can I do to fix this? I hate fighting with him and I just don't know what to do.
