Why won't my boyfriend take me to his friends wedding?

Hi,

For the past two months my boyfriend has been talking about his friends upcoming wedding. Now it will be in just two weeks and since he still hadn't asked me to go I asked him if he wanted me to go with him. I saw the invite and it's him plus one. We live together and are in a long term relationship. I've met his friend several times and we get along fine.

He got defensive and said he hadn't given it much thought. Then he said no he doesn't want me to go because he didn't 'plan on it' . What the hell does that mean? The wedding is here in town so what is there to plan? Am I right to be upset and think it's really weird that he doesn't want me to go? What should I do?

To anyone who was wondering why he doesn't want to take me: He said it's because I don't drink and I'm not a good dancer.
I like to dance, i'm not horrible but i'm also not the best. He's really into dancing (salsa and bachata ect) He said he just wants to have fun and he doesn't think he will if I go.
This pisses me off. He could still bring me and dance with other people if he wants I don't care and I never give him a hard time for drinking, it doesn't bother me. Sounds like a half truth

Hey all,
The truth as to why he didn't want to take me was because he wanted to take someone else. He didn't even have a particular girl in mind he just wanted to take someone else. The dumbass asked a girl who's friends of a friend of mine. He met her when he went out one night (about a week before the wedding) and told her was single and they started talking. He took her out to dinner a few days later and then invited her to the wedding with him.
