Banishing spell ? how can i remove someone from my house ?

answer: put your foot down and tell your husband it's the kid or you, seriously. He's picking his son over you, that's not a good relationship and he needs to see that. Be calm and say just what you did here, the son doesn't respect you, your husband or the house and he's not welcome until he does (which will be never). If the boy is over 18, he can get a life.
