"that" relationship was unhealthy for both of us but its demise doesn't preclude a new relationship. If a new relationship were to develop it would have some boundaries from the get-go, with counseling being number 1 on the list.
I'm feeling ya on this one, labug. I've been thinking,too, that my W has not been all-in for several years. She started throwing out the D word several years back when we had an argument. That's a good word to put me on eggshells. Bottom line is I would need to see a strong level of committment for starters.
