Trying to hard?

I was going to spend 500$ for my boyfriends birthday so that he and his friends could have a good time so they'd like me. They proceeded to tell him my idea was dumb and took over. Last time I went to their party I hung alone in the back round kinda wanted to have something that I would be included in. My boyfriend took their side and I'm kinda hurt. He knows this because I got tipsy and told him what I thought
