My real father abandoned my mother when I was 1. She married a military man who adopted me, then she got divorced from him and married another man who was highly abusive. She got divorced from him, but died when I was 8. Lived with my Grandparents for a short time and then was put in foster care. Ran away from foster care when I was around 16 and went back to live with my Grandparents until I was 18, at which time I joined the Navy and served for over 20 years.
Never went to prison.
Never took anti depressants.
Never committed a violent crime. Have had to defend myself, but those were extremely rare occasions.
Never was a juvenile offender. Yes, I did some stupid stuff that I never was caught doing, but most kids I know did small stupid things as well, even if they were in a nuclear family.
Runaway? Yes. But it wasn't because of the single parent thing, it was because I was in a crappy foster family. And yeah, the foster family was a husband and wife who had been married over 15 years, had a daughter and a son, and was pretty much your basic nuclear family. But, the reason I ran away is because the family thought I was free labor, and used me as a way to get money from the foster family program. Got tired of being used for a meal ticket and that is why I ran away to go back to my Grandparents.
Served a full career in the Navy, and managed to be awarded several medals, some were Navy Achievement medals. Also have managed to be a good citizen and a decent adult. Have 2 boys who, although they experienced their mother and I divorcing, have also turned out to be pretty decent individuals.
Maybe coming from a broken home can have negative effects on a kid growing up, but, I've found that it's more about what the kid decides to do with their life (like in my case, as well as my sons) that has the most influence.
And no. Coming from a family where the parents are a gay couple doesn't seem to have a bad influence either. Had a friend I served with in the Navy who was a lesbian. Her and her partner raised a daughter, who turned out to be pretty well adjusted, has a family, and is a productive member of society.
Maybe myself, my sons and my friends are the exceptions to the rule, but I don't think so.
