Welcome. I'm sorry to hear your H has little interest in your D. For me, it is a no-brainer, but unfortunately for others it is like pulling teeth to get them to be involved in the lives of their children.
I'm surprised on one hand and not surprised on the other that my W doesn't want me to have 50/50 time w/ D. On one front, I'd think she'd be overjoyed to know I want to spend that much time raising my D. On the other, for her to give up 50% would mean she'd also have to give up control. She is the one w/ the control issues in our relationship, even though I do have some history w/ it myself. However, if she loses that control, she wouldn't know what to do.
The loss of control may cause her to have to face her drinking problem instead of denying it as she's done since high school.
Thanks again for joining and I hope you'll come back by often.
