I'm kidding... I've been married forever and only really have 2 exes that I dated for any length of time. One wanted me to move with him to Virginia (closer to West Virginia) and I wouldn't go. I was young, just graduated high school and he was older. Soon after, he got a girlfriend and graduated to hating my guts. That girlfriend eventually became his wife then his 1st ex-wife (he's in the process of divorcing for a 3rd time now). I was friendly with the rest of his family and when his younger brother died, my husband and I were right there. His younger brother was good friends with my sister. We are friends now – but there is zero attraction – more like relief.
The other guy was somebody I lived with and he was physically abusive…. Or rather became physically abusive after I moved in. I moved out while he was passed out drunk…. About 3-4 years ago (might have been longer than that) he walked up to me at the store… my husband was close by and he apologized to me. Even still, I wouldn’t go out of my way to speak to him. He’s another that is getting his 3rd divorce. His parents are friends with my dad… which is awkward.
IMO, you only live once... and we are only here a minute so no reason for hating anyone… but there are instances where it is best to leave that ex in the past… where they belong.
