Would you stay if so doesn’t want marriage?

Hiya!

We are 4 years into our relationship and he’s told me he never wants to get married, that he doesn’t believe in it.

I asked him whether a quite ceremony with close family friends would be consider it then, he said “your wasting your life on me if you want marriage full stop”.

He is happy to have children but not to get married, I’m really not sure I don’t want children without being married. It’s a deal breaker for me and he knows that.

What shall I do?
