“Go with the flow”

So and I fought and before the fight we talked about ttc and moving in together, him being in my toddlers life, etc

Today I asked him if he still wanted to move in together and he just said “let’s just go with the flow” ummmm okay.

So you tell me every day how much you love me and how you never want to lose me and how you want my babies and now you’re distant and want to go with the flow when I bring any of that up?

I’m really shocked and it’s kind of turning me off from him.

What should I do?
