Am I a total bitch for this ??

So my 25th birthday is on Friday. Yesterday my boyfriend of 5 years said he made reservations at 8 on Friday. I was super duper excited. We have never done anything special for Mother’s Day, my birthday, anything like that ever so I was super excited. But the more I thought about it, I thought we don’t need to go spend a couple hundred dollars at dinner you know? I was thinking maybe going to Dave And Busters would be cheaper and sounded super fun. So tonight I said hey maybe we should cancel those reservations and go to Dave and busters? Maybe we can invite your brother and sister? And he lost his mind. He said of course I didn’t want to go with just him. I never have fun with just him. Just a bunch of UNTRUE shit. And any time we go on a date or ANYWHERE he’s trying to invite his friends and I never have a problem with it. I ended up saying no it’s totally fine we can keep the reservations and just go ourselves but he layed on the opposite side of me and wouldn’t cuddle with me. He said I’m in the wrong, I need to apologize. I said I’m sorry if that hurt your feelings I was just thinking of ideas and I even said never mind and him and I could just go. I didn’t think it was a big deal. He ended up saying if I want to go with other people then I can just go cause now dinner will just be unenjoyable and awkward…. I feel really bad now.
