Feeling used..

I’ve been with my fiancé for over a year now. I have two kids and he has one. Every dime I get, I put it towards all the kids and what we need and save it. He has literally never bought anything other than food for me, his son or my two kids. He is currently making like $500 a week at his job and I’m unfortunately at home, collecting unemployment due to Covid-19. I’m also pregnant. I have saved most of what I get so that way we aren’t struggling too bad. My problem is, even when I was working, I never made as much every other week.. and I still made sure he was straight.

Earlier, we went and bought a car cover for the suv and it was like $70 and he had the nerve to look at me and say “ if I need anything, you got me right?” Like, wtf? I’ve always had you, but you’ve never had me. Or maybe it’s because I’ve never asked him for anything. I just feel like I’ve done so much for him, that he doesn’t think he has to do anything for himself or anyone else. I mean, like I said, he doesn’t even buy for his own son... idk.. am I wrong for feeling like I’m being used.. or take for granted? Am I taking all this the wrong way? I just don’t want to get mad and cause an argument over this..
