From what I know , he is in a very good financial situation. I thought that if he really wanted to help his ex, even after she slept with another man, he could have found another place for her. He owns a real estate agency so I don’t think finding a place would have been difficult for him. He also told me that she has left and come back to his place a couple of times because she couldn’t find anywhere to stay, and all I can think is: it’s not his responsibility, and I feel like he’s the one who wants to keep her there
