Getting pregnant

Okay ladies I need help 😢 I really want a third baby but my fiancé is giving me a hell of a tim coming to terms with it. He doesn’t want one and I don’t know what to do!!! We got in a bad fight over this and we almost broke it off. We put getting married on hold because he said if I wanted another one we would have to wait to get married. Keep in mind we were suppose to go to the Justice of the peace to get married last Monday. Now things seem so different between us since we had that melt down.... he didn’t help with either of my boys so it’s not like it would change his life or schedule but he’s still like no I don’t want one right now I’m really hurt he doesn’t want to extend our family for one last baby. I just don’t get it. I stopped taking my bc and he knows that but he makes sure he wears a condom now because of m stopping my bc. I’m just at a point where I think we want different things and this won’t work. I’m 26 and my boys are 4 and almost 2. I don’t want to wait forever to have another one he says he wants to try next year but I know how that will go, he will come up with an excuse by then not too... he says if I give him all of my tax return then we can talk about a baby. I shouldn’t have to pay him to want a baby!!!
