Yikes Ardy! - Lady Clown
So so glad you don't have to deal with that anymore!
All I can think of is ....
your poor friend 
...
I hope he has gotten some help like psychological counselling, alcohol counselling and possibly medication... If he is a real sociopath... it is a behaviour that repeats over and over with or without having a partner. (in his case a wife) ... Thank God he took the attention off of you though for sure! Nothing scarier than a situation like that... and good on your kids for all the support they gave you
