I need some advice. So here's the sitch. I e been out of the house a month now. Done a lot of soul searching. My 180s: Validate, no expectations, no anger/intensity, focus on the needs of others (kids).
We were virtually no contact for 10 days. She started texting me for the first time on Friday. Prior it was email only. I've never initiated the texts, and have usually ended them. But her tone has been warm- not loving but friendly.
Her last text was "I hope we can still be friends"
How do I reply?
Remember- If reconciliation is ever possible it will be a long way out. And may be no chance. But how do you ever know? I am working hard on myself but know I haven't grown as much as I need, I'm still not consistently detached, etc.
my DB coach says to focus on the new relationship: collaborative cops rents with mutual goodwill raising the children. And from that partnership over much time she may see changes and want more, or she might not. Worst case at least we have an amicable divorce.
So with that in mind, how should I reply? I love her, I don't want her as a friend and long term if that's all wed have that wouldn't work for me, but I'm a long way from writing this off. Help!?!
