Wife / Girlfriend rage

My ex the mother of my son, was a control freak, who knows how my life would have turned out if I had stayed with her. My son is an adult and I have told him "we would have never been able to stay together, there was no meeting in the middle with her she's too controlling" he has since figured it out and agrees. I do always ask about her when I see my son though. Just a general "how is your mother doing...?"
I have a couple friends that were married to control freaks.
Both were married over 30 years. Everything in their life was controlled by their wives.
Unfortunately, they both lost their wives due to illness.
It's sad to see my friends going through life not knowing how to pay a bill, when to pay it,
and just being able to survive, they are completely lost.
