tired of begging for sex.

I've been dating my bf for six yearsand he won't get a job, and hasn't done anything positive for his life. He doesn't even take care of his daughter. This been going on for years but recently I'm tired of begging for sex. I'm always asking for sex and he shuts me down. I finally flat out said, "I'm done begging for sex. We only have sex on ur terms and I don't cheat. I'm breaking up with you and having sex with some one else..... I'm I wrong??? 😞
