Not wanting marriage- need advice

So I’ve been dating my boyfriend for a while and we have talked kids and I moved to his state as we were in agreement we wanted more than just dating. My impression was that marriage would be down the road and now a few months after moving to this state I find out he doesn’t not believe in marriage. I have made small comments about marriage as my best friend was just married and my other one is wanting to be married. No comments against what I was saying but he claims that the one convo he said he didn’t see himself having a future with anyone till he met me. I asked why there was no mention of not wanting marriage if that’s how he felt and I have brought things up and got no response. He feels a commitment is good enough and doesn’t need it to be legal. I explained what that means having the marriage and he feels as though he is committed and that’s enough. I don’t know how to feel as he is everything but that commitment means a lot to me to know that he for real in wanting me in his life. Wanting peoples thoughts on this and if I should let it go and know I’ll never be married but I have this amazing man or if I should stick to what I want and potentially lose what I have? I just don’t know how to feel...
