I literally have no opinions on marriage or children. Can anyone relate?

Okay so here's some perspective. I'm almost 20 and the guy I've been seeing is 28. My family loves him. His family loves me. We have a good time together and we really like each other. It's way too early for "love" but I could definitly see us getting there. I come from a religious family. I believe in God and consider myself Christian. He is agnostic, mostly because religion was forced strongly upon him when he was young and now he resents it. Despite this he still respects my faith. I have no real opinions on marriage or children and have no clue if I'd take part in either of those. As of right now, I feel no pressure to decide if I want to get married or have children one day. Not just with this guy, but in general. He is very much against marriage and does not want any children of his own, but has considered adoption. This doesn't bother me in the slightest. He says he'd still love someone monogamously for the rest of his life, but he's witnessed so many divorces that not getting married would just be easier.

My mother and pretty much every woman I know says that his opinions and his lack of religion should shake me to my very core. Apparently if those values are instilled in me, then it should have shocked me. I don't agree with the fact that every woman should be expected to get married. Or have children. It really doesn't bother me and everyone is making me feel weird for it. I know I'm young and that's why I don't really have opinions or thoughts on that stuff yet. And when I do I respect myself enough to get out of a situation that's going to prevent me from having the life I want. But for right now I have something good going with this guy. I believe that our religious views can be different. I believe that I can still be happy without marriage or children. And I'm not willing to risk the chance that this could be everything I ever wanted/needed over what's expected of me.
