My neighbors are forever telling us there business

My neighbors just moved in and there having issues. Let give a little back story both him and his wife were on drugs at one point and time. Furthermore he has his own construction business which is very successful. They both have kids from previous relationship but the thing is she keeps leaving him for no reason. He brought a house and everything for her and made upgrade to fit her taste. On top of that he quit doing drugs just to win her back and she keeps leaving him and the kids. She has done this on multiple occasion. My response was maybe she not use to the neighborhood that we live in or either she cheating on him.

Also on top of all this the wife keeps coming back any time she wants too and acts like nothing every happened. I'm just not sure why he keeps entertain he wife if she doesn't respect him and all his hard work. Personally I know and I think we all know a few woman that would love to be in his wife place sitting at home or going shopping all day while the man bring home the money.

What are your thoughts on the situation?
