HELP❗️⁉️

So my SO and I are looking at houses and getting ready to buy. I will soon be a certified EMT (emergency medical technician), and it’s hard to find a job as an EMT that pays well. On the other hand I love kids and have wanted to babysit for a long time just never really have gotten the chance unless it was my own sisters. And I don’t mean run a daycare, but just babysit like 6 kids in my home. There can be some real benefits to doing this, such as claiming some of the things you buy on your taxes and your utilities and etc. Plus I’ve told my SO that when we have a baby, and others, I would like to stay home with them other than just the 6 weeks work typically gives you. And we wouldn’t have to pay someone else to watch our kids such as a sitter or a daycare if I was at home. My mom did it, my aunt used to do it, and my other aunt currently does it AND my SO’s grandma does it. So what I’m getting at here is my SO absolutely hates the whole idea. Pretty much because I don’t make a whole lot of money like he does (which I’m trying to figure out a better way) so he is putting most of his money towards “our” home and he says he doesn’t want me to “run a fucking daycare at his house” and that I’m basically just using him to run the fucking daycare. His words. Which he’s totally wrong, I’ve wanted to move out for well over a year and a half and just thought of actually doing this the other night and start doing it, maybe 6 months after we move or after we have our first baby..

We were having a great night, laughing messing with each other, had sex, and I wanted to talk about it with him. Which I had told him hours prior to this that I wanted to talk about it later tonight. And while I was talking he was yelling at me with his finger in my face that I won’t ever have a real job and that I’m not going to run a fucking daycare out of his house. And that as soon as we start getting serious about buying a house I want to do this. Which I honestly just had the idea the other night and really liked it but he won’t even give it a chance. I’m honestly at a loss right now I feel helpless and that he can’t compromise on anything and that if I like something he has to go the complete opposite of me. Idk I just need help, please.
