I just don't want to come across as so unloving that it pushes my W further away. Anyone who has gone dark can probably understand, just looking for advice/opinions/encouragement on this. Curious if I should go as dark as possible or if I should respond to texts about our D2. Confused.
Your W definitely wants to keep you attached, so she uses D2 b/c she knows that will get to you quicker.
I don't disagree with Matt. Another option would be to learn how to use as few words as possible. Instead of stating a sentence, send a smiley face or some other face. Try one word answers as a response. That way, you aren't ignoring your D2, but you aren't carrying on a conversation with her.
I really don't think your W is ready to cut you lose yet, and that's why she's playing these games. She still wants this interaction with you. It's common with many WW's, especially younger women with small children. Even though she's file for D, she wants to keep you on the other line. Maybe it's her backup plan, in case OM doesn't work out, so you need to work at emotionally detaching. In some cases, it takes more of your energy & attention in watching how long to wait before responding to her text/photos than just getting it out of the way. Know what I mean? Using one word answers or emotion symbols may help you.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
