If it's any help, op, yes he won't have any issues finding someone, but as someone said, will he STAY happy?
An ex of mine (late 90s) was very charming, and was (back then) good looking. I was devastated when we split. Especially as he'd completely broken me down in so many ways, including my looks. He enjoyed dangling in my face that he'd married the woman he left me for.
Well, 2 decades later, my son (not this guy's, from my marriage in the mid 90s) ran into this ex's daughter on a night out! Ridiculous coincidence. Anyway, she told my son enough to find out that this ex had done exactly the same thing to the woman he left me for. Treated her horribly, cheated, left her gobsmacked, etc.
To say that I had zero sympathy is an understatement, as she was more than happy for him to walk out on me for her back then, and as I recall she found it rather funny when he left me for her.
Honestly, no one can say with any certainly who your ex will end up with, and if he makes it work or not. But he won't have any problems meeting anyone, no. It just doesn't work like that.
