I am happy for you; I hope your approach works. Your situation sounds similar to mine; my W always has believed she was unlovable, a wound from childhood. Now that we are physically separated (have been for five months), I wonder if I too should pursue a bit more even though she says she wants space. I've given her that in droves. I've avoided begging, crying, pleading, etc. and all the other things everyone says not to do.
Still, here we are with no movement. She doesn't talk divorce, but she doesn't talk trying to date, talk, etc. She doesn't say much at all. I strongly believe she is in MLC depression. I'll own my failures, but this goes deeper than my faults as a person/husband.
She knows some of my new activities since the separation. I am hoping to attract her back, but I am starting to wonder if a new approach is needed, something in addition to the good GAL activities that I have pursued for myself.
So, what does pursuit, but not "too much" pursuit really look like???? I'd love some concrete examples, because as you and everyone else says, it's a fine line between confidence and neediness and other things that will, according to the experts, drive them further away.
