What does being a disservice in a relationship mean!?

My boyfriend & I just got into a huge argument about bills & money, and he told me he feels like he's doing a "disservice" to me. I'm currently out of work & he is paying for a lot more than I unforutantly can right now. It's hard as it is but then he just blew up on me about finances... :( I don't know how to feel...
