I guess i need to vent and not feel attacked for once

So my boyfriend and I have beautiful kids together and our biggest argument for our relationship is money.. Because he just doesn’t like to work, I am the main provider and i make the most money. But one of my friends work with him and he’s always volunteering to take work off, and it’s like all these bills are due and it’s starting to tire me down.. I’ll work 14-15 days in a row just so i can stay ahead because he’s constantly missing work and taking it off. But doesn’t see a problem in it.. It’s so exhausting. I’m tired of it. Then here comes taxes and he feels like he should be able to claim a child because he’s their dad, which i don’t think he should. So am i over doing it or do y’all think he should claim a child too…
