Hi Mandee,
I'm am sorry to hear of your situation
I can not offer relationship advice, as I am not married.
What I can say is that, my parents divorced when I was 2, my mother remaried when I was 6 sadly that did not last but a few years. I was extreamly close to my setp father, and thier divorce was pretty hard on me. Not as hard as for my mom though, seeing her sad was the worst part for me.
Now at 26 I have found that I have always been attracted to good fathers and great husbands! ( mind you, I have never been a homewrecker, just admired the husbands/fathers!) This has turned out to be a positive in my life, as it has kept me away from some totally bogus guys! Now that I have been in my relationship for 5 years I can think about marrige and take it seriously. I think I waited so long because I saw what my mother went through and I did not want to feel her pain.
My mother is my hero and my best friend.
It might be hard for your daughter, but you can make it a positive for her by being the best, happiest mom you know how to be! I know she loves you and would just want for you to be happy. So do what will make you satisfied and give you your worth as a woman, that is the most important thing you can do for yourself and to teach your daughter.
If I may be so bold as to quote a scripture that gets me through every day:
Joh 16:33
These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world
