Well one thing is for sure. If anyone knows how to put effort into making a relationship work it's you. Some day there is going to a guy who will feel like he won the jackpot when he finds you.
But for now just take care of you and focus on further healing and growth. Eventually you are going to feel very free and "whole" once the pain subsides. It is going to be a huge relief.... life will be good.
Take care of YOU first and foremost, do what you need to insure that your daughter's best interest both emotionally and finanically. Stay logical. And, when in D make choises that are best for YOU and your child.
There is no arriving, ever. It is all a continual becoming.
