For 2-3 years I'd help him, who's unemployed, financially, such as staying at my apartment, paying for the bills, and loaning a car, but he's always reckless with money and always in debt despite promising me 2-3x to not loan again.

The breaking point was when he didn't allow me to go to the apartment because of personal space, and I can only rent a very cheap motel for a 7-week holiday (that its hard to get from my workplace). The room has black mold, dirty, and no chair. I'd get itchy. It's so bad to the point that I get really sick. I'd chat him about the room and me being sick, but no reply. Waited for a whole day, until I rant to him about me having to save up, can't buy the clothes I want, because all of my money went to his debt.

Still, no reply until the day after. Called him multiple times, to which he didn't pick up. He chat me to stop bitching. Then I decided to break up through chat, saying that I won't pay for his debt anymore.

Right now I feel conflicted, if I keep this relationship, I'll never be happy, but I'd always feel pity for him because of his debt.

AITA for breaking up?

Edit : forgot to say but I'd always go back to back my apartment and parent's house due to work. The reason for the apartment is because I want to get away from the toxic household. But yeah, I'd pay the apartment lease and bills.
