<human>: My [21 M] girlfriend[22 F] and I have been together almost 2 years, and we talked about the future (marriage, family and whatnot) and she told me explicitly what engagement ring she wants, and said if she gets anything else she would be upset because it would show I don't know her. Marriage is not in the near future and we both agree on this because we're both barely out of college and want to focus on becoming real adults LOL, but the fact that she said she wants this ring to get married (and it almost sounded like a prerequisite to my ears) worries me, because to me it seemed like she values the ring more than us and our future (that actually kinda sounds ridiculous now) and it's a very expensive ring, at least more than the average ring.

I know she loves me but this attitude towards an engagement rings bothers me; do women typically choose the engagement ring? I guess I see the ring as something the guy picked to show how much he loved her and show what he thinks of her. I would almost definitely get her dream ring (depending on financial stability at that point of time) but the way she says it needs to be that ring makes me wonder. Am I being unreasonable?

Can you condense the text into three sentences or less?
<bot>: My girlfriend says she would be upset if I pick any engagement ring that isn't the one she chose, and this concerns me.
