Relationship advice😅

Okay I’m just going to put it all out there. I need input and advice. Okay, so I have a 2 year old daughter. Very wild, outgoing, smart and beautiful of course! Well, I have been through a divorce, and am currently engaged now to get remarried. The wedding was originally set for this year, but he called it off. He has lots of issues with the way that I parent my child. He says I don’t get onto her enough. She doesn’t respect me, etc. but she’s TWO! Remind you, he works nights so he’s usually only around her on weekends. He says he called the wedding off due to us just needing to get on the same page with things. I just need advice. I feel like I’m trying my best to be everything he wants me to be and change and do better, but he acts like he’s miserable just talking to me. I’ve asked him if he wanted me to leave because at times I don’t feel wanted and he says he wants me to stay and he does love me. But to me, sometimes it just doesn’t feel that way. I just need advice on what you girls think about this.
