I'll ask you the same question that none of the ladies here answered. Would you prefer to be with a guy who wants your heart, body, and soul, or would you want a man who only values your womb? The way I see it Harry kind of took his wife for granted. He didn't make her feel desired or loved. Based on her comments in episode one he didn't make her feel tha way. His whole purpose for having sex with her was about having a baby. He took love and pleasure completely out of the equation. That is why she felt disconnected form the relationship. While Dom made her feel desired. They have a mutual connect that Harry just doesn't have with her. Dom values Savi and only her. If it's his baby that's just a plus. While Harry only values the a baby. The same thing that ruined her marriage will be the same thing that will bring it to an end. While the same thing that cause Savi to be drawn to Dom in the first place will allow their relationship to progress.
