Would you stay with someone if you wanted marriage but they didn’t?

I’ve just had my first baby, he’s 4 months old. Me and my partner have just been talking about marriage and it’s something I want in my life but he doesn’t want it as he doesn’t see the point in it. Bare in mind he’s been engaged in the past.

It’s something I really want in life but he’s saying he really doesn’t but he’ll do it just to keep me happy.
