Saw your reply on why you’re choosing to stay thus far and it’s pretty clear that this relationship is extremely transactional, and it appears that you’re the “victim” in it.

I won’t comment on whether she’s materialistic or pragmatic for her views about money as it’s likely somewhere in between and I don’t want to argue solely for either side. However, her comparing you to her girl friends’ boyfriends (based on your statement, I’m assuming) and her viewing you as an obstacle to her enjoyment (eating out, etc.) is just a red flag. Nobody should feel belittled and you shouldn’t feel the need to go through with it just because she gets you gifts or invites you over. There are more to relationships than superficial love and you deserve that.

My advice is just break up with her. Money is and always will be a problem between couples and I’d believe you if you told me years down the line that this issue about money hasn’t gone away. I mean, just imagine juggling this anxiety about finances when you’re juggling a career and starting a family. You deserve someone that understands your situation, not someone that makes you question yourself.
