Updated: Disagreements on decisions for our baby

So my boyfriend and I talked about baptizing our baby bc he’s baptized and I’m not. I’m not against it or anything but we don’t practice any religion at all and I want her to be able to decide for herself. He originally agreed but then today he changed his mind? He said he’s going to baptize her no matter what I say and I’m like wtf we talked about this already and came to an agreement. He was super adamant and defensive about it. I don’t think it’s fair for him to go back on our agreement after we both said our reasons and came to a decision together. I’m not sure how to handle this? The thing is he’s baptized but doesn’t practice or anything, his parents just baptized him when he was little. He never goes to church or even believe in the Bible? His words.

I believe it’s his mom pressuring him to do it bc she was upset when we told her we’re weren’t going to, she got very judgmental about it. And to re-explain myself. While no im not against it, it’s something that doesn’t feel right to me as we don’t practice so I’d feel fake about doing it. Our families are Hispanic so it’s always more of an excuse to have a big party lol. That was one thing he said when we talked about it, was he wanted the party afterward. If we were doing it for the right reasons and it was something we believed in then yes, but it’s not.
