I sent an email to stbx about possible visitation schedule revisions because he stated that he'd like to see D more than just on Wednesdays and every other weekend. He seemed appreciative of my suggestions and seemed amenable. He also discussed being flexible if the other parent needed a whole weekend or whatever... all in all, not bad.
I also stated that I knew he wanted to discuss our sitch and asked how he'd like to go about that.
He said, "As far as discussing our situation, I get a strong vibe you don't want to talk to me in person, and I know you're better when you can form your words in your own time. So I don't mind writing you another separate email if you prefer. Let me know."
I think I'd rather talk in person rather than read a whole unending diatribe.
