Your situation sounds similar to mine. Do you let go and walk away and start a fresh or do you try and build a friendship and see where it leads. Having you close by but in a new dynamic will suit your w as she can have you as support when she needs it without the pressure of having to cater to your needs.
I have 2 young D and my w is happy for me to see them anytime to maintain a "family" environment. I want her back but the problem is that this could become normal and never develop further. Something has to give.
When my w left me 5 years ago, she started dating other guys and I was always there to pick up the pieces. I visited the house 3 times a week and even went on "dates" with her as friends. It was only when I decided to move on and date myself and her realizing that her life wasn't that great and there was a chance she would loose her support, that she almost immediately decided she wanted to give the M another try.
I think it's a fine balance that only you can determine as you know her. I would suggest going on family days out but only focus on your daughter. Maybe compliment your w when you first meet up and then show her the fun, happy Dad. That's my opinion right now but obviously I am in the same sitch and trying to figure out new techniques before throwing in the towel.
I gotta keep breathing. Because tomorrow the sun will rise. Who knows what the tide could bring?
