Nicole, I understand you fully dear. It must be so hard to be a single mom while both you and your D are sick. And wanting your D to have a father while you may or may not have a H is also just and exactly what a good mom would want. You seem to have a lot of forgiveness for your H, at some point though stop giving him the benefit of doubt. It may be hard for you to detach if you still want to find some reason for his irrational behavior.

I think Jim has a good point, may be start sending your D to stay with H for one night at a time. This may help them build a stronger bond and give you a much needed break.
