Would you stay with a cheater bcs of the lifestyle he can provide?

My husbands business partner has been married to his wife for 8 years. They have 2 kids together. He takes off to toronto every few weeks and it’s common knowledge that he is cheating on her there. He turns his phone off for the 3 or so days he’s there and returns home like nothing has happened. I told her I wouldn’t stand for it but then she basically said to me, he’s the father of her children and he is rich. He provides her with a $200k car, a $5M home and she doesn’t work and has a full time live in nanny. She spends money as she wishes and has a lot of luxury items. She thinks it’s not worth it to fight over it and she’d rather be taken care of them leave him for cheating. When they are together he comes across as a very good husband and father. He’s very loving and affectionate to her and their children.

So my question is...would you stay with a man that was constantly cheating just to reap the benefits of the lifestyle he provides?
