Well, my mom was married 4 times, and the first three, she married the wrong guys. Wrong by a lot.
Father 1: I never knew my biological father until I was 31 (33? I don't remember) I didn't miss much. By the time I met him, he was a broken down old alcoholic, looking to connect with his first born. I guess so he wouldn't die alone. I obliged him, and had somewhat of a relationship with him. But, only because my mom said I should forgive him and let go of the grudge I'd been carrying my whole life.
(step) Fathers 2 and 3 were both physical and mental abusers (father 3 had the added bonus of being a sexual abuser as well.) We lived in fear for years, and now they're dead and buried and I'm glad.
My current step father met my mom, and they married in 1987. She's never had to be cold or hungry or scared since. He's the only one I've ever called Pop.
