SAHM/WFHM w/lazy non-working spouse

How does anyone else cope when they're inside b/w 90-100% of the entire time. The only time I leave is when my sister or her hubby or my dad come by and take me out to run errands or when I take the trash out. Side note: my husband does not work and makes every excuse to not work. He cooks 4/7 nights a week. He is in the bedroom 80% of the time. He comes out to cook and then randomly leave. (Never offers all of us to leave and go somewhere together). My husband "watches" our son while I work from home. I use quotes because my son's sleep schedule is off because he has our son sleeping during those times so that way our son is up while I'm off my shift and then it's my turn to actually take care of him and watch him. Because my husband has our son in his bed (big play pen cuz he climbs out of everything else) and puts on shows on the laptop. And my husband sleeps or is on his phone or playing video games. We also have a wall divider so heavy only he can move and he keeps it up on days I work longer shifts. Like, keeps it up until next day after my next full shift. And sometimes when I'm in between shifts he'll keep the divider up. Then when he comes out he makes arguments out of everything. I can say "hi" or breathe wrong and he will start going off and then all of a sudden he starts saying how I don't do anything or care for our son and I'm useless and insignificant. How does anyone else cope with a lazy husband while working and living check to check to simply provide basic needs for your family, meanwhile living with the WORST spouse? (That's not even a grain of sand on Mars of examples of how my husband's awful. Cuz.... I can write a whole novel.... How do y'all cope? How do y'all make your husband contribute more financially when he relies on other people caring for him? Side note. When I met him, he had 2 jobs and was always working. He was so nice and had an amazing personality. Now he's the complete opposite. Like lazy psycho opposite.
