Any girls earning more than their partner & paying for most things?

So I just had a fight with my husband about money but it was mainly me nagging (he wasn't fighting back). I was having some resentment because I'm the one paying for most stuffs. My husband is the most loving man ever but he wasn't doing well and decided to go back to college. He's gonna graduate by early 2018. He works 4 days in a week (both weekends) while in school full time and the money he earns all goes to his car loans, insurance & his bills. He earns less than 1000 per month. I'm always paying for everything like a weekend trip, dinners out etc. if he gets a job after he finish school, he would potentially earn 50k/year. How do I cope with this bad feeling? I felt so bad to even bring this up to him but I get frustrated.. I know it's a double standard that guys always have to pay for girls etc. I am not leaving him because he's a good man and he's trying his best but I need some advice on how to feel better about the situation? Thanks!
