My girlfriend and I have been together for several months and recently moved in with each other. She moved into my apartment. I have a high-paying job, in fact, I make quite a bit more than her, and the apartment we live in is way under the budget I could afford. Because of this, I decided to continue paying all of the bills when she moved in. She's offered to help, but I refuse because it would be hard for her financially and it's not a burden for me to just continue paying on my own.
Lately, she's been saying that I don't love her enough or that she loves me more. I've been compared to her exes a couple of times and also compared to how my own friend treats his girlfriend. This is all concerning to me because I can't believe she would ever think I don't love her. I've bought her expensive gifts for Valentine's day and her birthday. When she is studying for school I have to stay up much later than I should have to help her when I needed to work in the morning. On top of everything, she knows I was reluctant to let her move in but decided to do it anyway because it was most convenient for her job. I thought it was too soon, but she really wanted to because it's much closer to a good job that recently hired her.
How can I tell her that I don't like feeling guilty when she says I don't love her enough? I'd like to just tell her that it makes me feel guilty and to please stop, but I know what her response will be. She will most likely say that I'm taking her words "too seriously" or she may just say "fine" then go silent. The latter I consider another guilt trip technique.
