Relationship and career balance

I’m still young and often times I find myself giving up part of myself in order to make my relationship work. I know that compromise is a huge part of any relationship but I have not yet figured out that balance. I give too much, put myself in bad situation all because I want to be there for him and make sure that he’s good. I don’t wanna work too much and never make time for us but also in order for me to get anywhere I feel like I kinda do have to put in a lot of hours. I’m still in schools and those loans aren’t gonna pay themselves on top of living on campus while he lives at home. He makes more than me but he doesn’t have the financial responsibilities that I do of making sure I have everything in the house(groceries and necessities). Sometimes I feel like he doesn’t get it. He’s living good because I made the sacrifices for him. Why does it sometimes feel like I’m in this alone.
