Am I over reacting?

Okay so Eminem is touring and he is coming to New Zealand which literally barely happens for us. He is literally my childhood music like absolutely no doubt, he’s always been top of my list as an artist. Anyway so, I told my boyfriend (of nearly 5 years) that I really wanted to go with him, he was so keen made plans for us to stay in a motel afterwards and what we could do the next day etc. and he knows how important this is to me so obviously I got excited af. Tickets go on sale tomorrow morning and he just told me he doesn’t want to go bc he doesn’t think he’ll enjoy it as much as me and he feels like he will be forcing himself to have fun.

I got mad bc we had made a full plan, I was so hyped and we had talked about it numerous times only for him to bail even though he knows how important it is to me. Then he calls me selfish for wanting him to go, but like I feel like it’s a sacrifice he could make for me, come with me and still enjoy the night with me but he’s too set on the fact that he won’t enjoy it. What upset me is that he knows how important it is and I’ve always wanted a man who would do whatever to make me happy bc I sure as hell would and do all the time for him and he’s made me feel like I’m not worth that 3 hours just so we could stick to the plan.

Also the plan was an anniversary plan bc it’s our 5 years around the same time so I guess it also feels like he’s bailing out on that.

He said he would still do all the after stuff but just doesn’t want to come with me to this part and I genuinely am really angry and upset. What do you think? Should I have understood him more?
