Sorry you are going through a rough jag. We all understand those moments.
Regarding how your relationship with your h started and how that impacts things today, I think when a man is interested he will do the hard work. If he is not interested in doing the hard work, then good; you weeded that bad apple out.
In the beginning you set a boundary to protect your daughter and good on you for doing so! H respected that and worked around it because it was the reality if he wanted to be with you.
How that relates to now? Do you want a guy you have to lead to you with carrot and stick? Do you deserve a guy who realizes he is a complete fool to let you go?
Continue strengthening yourself for you and your d. Make yourself who you want to be for you. Don't sell yourself short for a man.
