DO NOT agree to ONE thing (selling the house or anything else) until you have spoken with an attny.
The reason your H doesn't want to talk to his family has nothing to do with being influenced and everything to do with the fact he is involved with OW AND he left his W and children.
Be pleasant when you have to be around him but go dark. You are under no obligation to assist him with this plan.
As long as he is "talking" with OW he will not hear anything you say. His focus is with her now.
