So guilty of the same 'backslide' as you Sue. Not lately, but in the past. Yes. Sara is right. Don't beat yourself up about it, you are married to your husband and have a close bond. But I agree, don't let it hurt you.
I am so proud of you sweet friend, for calling and getting the help you need. My heart breaks for you. SallyM just emailed me this morning about how my H's waffling this 'late' in the game is making her mad. So true in your H's case too. He loves you Sue, it will be hard for him to find a 'balance' with you as his ex-wife. He will become angry and you will see more of the guilt thrown at you like last week.
You are human. We are all human. Please don't get so down on yourself. If you find it harder to do activities as a family (which I am lately), then gently encourage H to take D4 on his own.
