I want a baby but he can’t commit

So I’ve always known I want a baby and a family. But my current partner has commitment issues (he doesn’t want a girl friend or wife) and although he has never expressed whether or not he wants to have anymore kids. He hardly ever pulls out, it’s rare. He has been my partner for the past three years and I have not gotten pregnant this whole time.

I have pcos and and I’m in the beginning stages of hypothyroidism. I’m about to turn 30 this year and I feel like if I want to have children this is the time I need to start to focus on that.

Any advice? Is it wrong for me to end things because I want to have that commitment and family? Has anyone else been through this?
