Most Helpful Guy
Abuse comes from a lack of empathy and an insecure need to control and dominate someone... and since he doesn't care about you (ignore what he says and pay attention to what he does) then of course he's going to want to live with you... because he can walk all over you, and it's free. It's win/win.
Obviously do NOT allow him around or back in your life. Unless you're kinda into abuse and such.
