I’m so confused. what would you do?

So for the past week my husband and I have been fighting. To the point we both were very frustrated. He reached out to me and said he doesn’t want to fight. We have a two year old daughter. Part of the fighting comes from him telling me he wants more kids and getting my hopes up, but then refusing to try when the time is right. Again, today I told him I wanted to try and today and tomorrow are great days to do so, and he said that it sounded good. So I got our two year old down, got myself all made up, went to him as he was relaxing on the couch and was like hey let’s go! And he’s like no not right now. 🤦🏻‍♀️ honestly, I’m fed up. He’s saying he’ll do better, he’ll be nicer, he’ll try and be there for me but he’s more interested in napping, or relaxing than hanging out with me or even having sex. The last probably three Times I’ve suggested sex he’s said no. Wtf is wrong with me? I’m feeling so awful about myself.
