Different views on things

My sons father and I have been off and on for 5.5 years since our son was born. He’s been known to be a compulsive liar and cheat. However, he’s been showing me good strides and changes the last two months we have been together so I am feeling more confident than I have previously this early on. I am also in counseling and working through my own issues and our past issues. And we always end up back together even after dating others and can never seem to move on successfully. I know the past hasn’t been a positive but I feel like we have the potential to be good if we work through past issues and continue to be healthy together. We don’t plan for more kids right now- but down the line. And I’m struggling with the fact he only wants one more child. I’ve always dreamed of a lot of kids, minimum of 4. I don’t ever want to regret or feel like I’m settling. And each time I think of only one more, I get bummed but he is set in stone.
