BTW, thank God my dad didn't follow your last statement!
He is the ONLY dad to my older siblings (technically, half-siblings), who had a poor excuse for a dad who was actually married to my mom. Abusive (threatened, but didn't get anywhere - not with MY mom), adulterous, lecherous and just plain odd and seedy. Probably best described as 1 of those "good ol'boys" in the bars.
Mom made a poor choice (father warned her) young, got 2 children out of it in short time, left back to her parents' who helped raise her children while she worked, until she met my dad.
A woman of 29 with 2 sentient children. My never-married virgin dad didn't mind apparently, because he not only asked her to dance (not knowing she's a mother), but married her after only 5 months. And adopted the children, who asked if they could call him "Daddy" when they heard the wedding news.
And here we are 40 years later....he's still the only Dad my brother and sister care about. And at least he gave them stability.
Glad it worked out. I just don't want to deal with that kind of dynamic, and since I don't have to, all is good.
