I don't know if this will help or not, but hopefully it will give you some hope. I know two people who were "children of divorce" as the healthcare community seems to label it, and they talked to me after it became obvious my son's father was not in the picture, even before the actual divorce.
I'm going to use fake names just because I don't want to possibly embarass anyone.
Let's call him Guy - Guy's father left when he and his brothers were quite small. Skipped out, wouldn't pay child support since he never filed for divorce, etcetera - deadbeat dad stereotype. Guy tracked him down when he turned 21 and made him sign divorce paperwork so his mother could finally move on with some things. Guy made some mistakes along the way growing up, and as a result of cohabitation had a daughter. Beautiful little girl. Guy is now one of the best dads I know. This was a bad situation - Guy wasn't even sure the little girl was his, but he signed all the paternal paperwork and has refused DNA testing because he's afraid she might not be. Was an actual single dad, made formula, changed diapers, everything. Turned himself around completely for his little angel and it is kind of sweet and hilarious to see this tattooed guy playing with Barbie dolls and coloring Lisa Frank posters now. He knows I'm in education so is constantly having me check whether he's helping her with her homework correctly, stuff like that. Married to a wonderful girl who has completely adopted the child, I've seen wedding pictures of them all three standing there and the baby was so excited she was getting a mama and grandparents the same day. Guy told me that when he realized he was going to be a father he decided he was going to be the best father he could be, it's what a child deserved. He is also really supportive of his now-elderly mother, drives up several hours to check on her and do things like oil changes for her car, stuff like that.
So my other friend, let's just call her Lady - Lady had a dad who was in and out. Mom tried to accomodate the fact that sometimes he would pay child support, visit, make all these promises to Lady, then pick up the pieces when he broke them again. When Lady was little, it was little things like "We'll go to McDonald's next week" and then not showing, as she got older it got to be more like "I'll buy you a car for graduation" then not even showing up from the invitation to see the ceremony. She had a hard time trusting guys, but finally found a great guy who's in the air force, after a lot of waiting she decided to go ahead and marry him. Her father did show up to the wedding - and proceeded to hit on my sister, who was being one of Lady's bridesmaids and was the youngest of them at age 22, in front of Lady. She told me that was when she realized he didn't really care, and instead of being angry she just sort of felt sorry for him. She told me she kept hoping something would magically "fix" her relationship with her father, and that she kept trying to do everything better for years so he would like her, but that moment made her realize it wasn't her problem. She also said that's when she realized she picked the right guy to trust - her new husband came over and redirected her father away from my sister, then came to check on Lady to make sure she was okay and tell her she was incredibly beautiful. They've been married for quite a while now and though they haven't been blessed with children yet I pray they will be because they are so kind to each other and Lady does tons of charity work and is always still surprised when people thank her for it.
No, Guy & Lady definitely didn't have great childhoods. I think a lot of Guy's issues as a young adult were because he didn't know what a guy should do so he just followed the crowd, he is the one who told me to make sure my son had lots of access to my brother and my father so he could see what men should do. Both Guy and Lady managed to grow up to be kind people doing their best to follow their faith and do good in this world. I hope this helps, there are days when I get very frustrated because this isn't the way it should be, where is the life I signed up for? On those days, the best thing I can do is stop and say a prayer.
This one I like particularly:
"Show me what blessing it is
that I have work to do,
and most of all,
when the day is overcast
and my courage faints,
let me hear Thy voice, saying,
'You are my beloved one
in whom I am well pleased.'"
I hope this helps, hold on.
