How do I stay away from this guy

Hi I am in a one year 9mnths relationship with a guy who doesn't want to break up with his baby mama and keeps telling me he loves us both and can't afford to lose either of us and this drives me crazy, I want out of this relationship but it hurts so bad #i love him so much

hes going to play you back and forth with his baby mama and as long as he can get sex from the both of you, he needs to grow up and be a man you need to let go, sorry if that's not what you want to hear
