He's confusing me 😡

So when I first met my husband kids were never a problem. At least I never thought it was. He's so great with my son. (Previous relationship) He treats him as if he was his own flesh and blood. Now here's the thing. And the point where I'm so confused. He tells me he doesn't want kids but he refuses to pull out. I try to pull back when I know he's about to ejaculate. But he holds on tighter. He does Lil things like rub my stomach and say hey you in there. Are u sleeping in there? Please come out looking like daddy. He asked me yesterday if I wanted more kids and my answer was yes. He said nothing else. Until I asked will he give me a child. He says no and starts laughing 😡😡😡. He's totally confusing me and pissing me off. Its starting to depress me. Divorce has never crossed my mind but now I have it in the back if my mind. I want more kids he says he doesn't. Where does that leave me? And why does he act as if he wants children and says he doesn't? +He has none of his own). I think I'm gonna go on birth control without telling him anything until u figure out what I'm going to do as far as staying in thus marriage. I don't want him to feel as if I'm trapping him. Even tho he doesn't like to pull out. I'm so lost and confused and angry and depressed. I need some help.

Anyways thanks for listening glowers.
