Coach, I think you're sitch sounds a lot like lola's.
I tried to go dim with my XH but I couldn't seem to do it well. Having a 6YO doesn't make it easy. I contact him much less now but I know he still finds it a little excessive so I really am trying to cut down even more on the calls and texts. I think it also depends on the topics that you bring up. MY XH will talk and joke with me but I better not ask any questions or come across as controlling because then he shuts down.
If you think going dark would be damaging to your sitch then don't do it. It's not for everyone. Dim however is a good option because it doesn't mean you can't contact her. You just do it lightly and not very often.
How often do you communicate with her and what types of things do you talk about?
