He is doing everything he can to show he doesn't want a baby

My fiancé says he wants children as much as I do, but Im starting to think Thats not true. He doesn't outright say it...but Im worried about his actions. He starts fooling around with me...then says "can I just have a blowjob tonight? My back is sore from work." and has done this multiple times during my peak week. He started a new job and we choose the higher end health insurance plan that covers pregnancy. ..and he "accidently" told his work the wrong one so Hes enrolled in the cheaper plan that doesn't cover it. We are trying like hell to save money for our wedding and a baby but Hes been calling into work frequently which means I have to pick up extra hours at my two jobs and go to college full time to break even. He said the other night..."Im marrying you for you. Not kids." and while Thats really sweet, he knows how bad I want to be a mom. Hes developed this "who cares" attitude and its breaking my heart. Idk what to do or how to talk about it. If he doesn't get on board with the baby thing and start supporting me a little better, it might be a dealbreaker. We've been trying for awhile and are trying to accept it may not happen with fertility help but Hes made comments that he doesn't want to put a lot of money in conceiving. And Im basically the bread winner cuz I bring in a lot more monthly. I hate this wondering. ...
