Okay I may rick the boat a little. Because I kind of disagree with you Rob. I think Sue would be working on herself, thinking of herself if she voices to her husband that this is rude! That his behavior is rude. That his actions are rude! That his continuing to talk with another female and possibly sleeping with her is rude and wrong. Listen there HAS to come a point where the spouse being cheated on stops acting like a doormat to the cheating spouse. How can a man or woman really respect the spouse that sits around and plays nice and doesn;t say a word. They just cat as if in hopes the wayward spouse will come back to them. To me that doesn't show much self love or very much respect for yourself. Communication is the key to any marriage. Without a marriage will never survive. So by holding in your true feelings you are denying the marriage that open communication.
I agree I think Sue needs to work on her. She needs to detach. I can see her worrying about his every move and action. She needs to take care of herself and get to be where she should be emotionally for herself. But maybe her having that talk with her husband is her doing just that. She is respecting herself and wishing to call him on the carpet for the nasty way he is treating her right now. Maybe it could open his eyes a little.
But I have a question...do you honestly believe the wayward cheating spouse will actually respect someone who acts like the one they love that is cheating doesn't hurt them or effect them, like it doesn't bother them? I'm sorry but to me the wayward spouse may think the spouse doesn't care so maybe there is no hope. You can't respect a doormat. I don't say that to be mean or hurt anyone here. But also I have seen a lot of people at least state their views on this to their spouses with the most amazing strength and self respect for themselves. I don't think Sue has had this chance yet.
