<human>: I've [m/25] been with my girlfriend [f/21] for almost three months and a couple of days ago had our first serious talk about what we want in the future. We discussed our shared interest in having children (eventually in the distant future) which was great, but the topic went to marriage where we hit a snag.

I've never been interested in marriage. I'm not religious and I find the idea of marriage an old expensive concept where you show your love through a ring. I completely understand that to a lot of people marriage is more than that but for me I feel as if I can show my love and commitment for a person in many other ways. I don't need a ring for that.

My girlfriend has been the type of person who has wanted to get married since she was a young kid so hearing me say that made her upset. We didn't argue about it, hell, she even said she understood why I didn't want to get married and would never want me to do something against my will just to please her. She has been extremely level headed with the whole situation. 

Since then (roughly a week) she has been very distant in terms of communication, enthusiasm, and every other aspect of the relationship and its clear that its affecting her. My question is how do I deal with this? I hate not being able to give her what she wants. I can't go through with a marriage I don't want, even she knows that and I doubt she would want to if I said id do it just to make her happy. 

I feel the only logical option is to split up and let her find someone who will want to get married, or am I being silly? I know its not the biggest or most interesting post on this sub but I just want the best for her and need advice.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: – My girlfriends wants to get married, I don't find marriage important in a relationship. She's devastated that she won't get married.
