I am sorry. My suggestion is same as before. Keep your time in his house to a minimum. Go do other things the rest of the time. His kids and ex are right. I am sorry and am hurting for you.

Is he paying you? I most certainly wouldn't expect payment from loving friend or family but if I am treated like crap I'd look at it as s job. Hang in there. You are a good person. I wish you lived close by. I'd take you out for lunch or see a show, just to get out
