You gotta get back to that place where you're happy-go-lucky. Somehow. I bet your kids can see that Mommy is the one pulling away.
Sounds like you're doing a lot of GAL & 180's but ... detaching, truly detaching, is not happening. (Same for me! Not sure I'm truly detaching). Sounds like your happiness is still directly attached to her behavior.
Glad you still think your W is hot ... that's essential.... to suffering.
