Good to hear you're doing well too. I would not have any interest in meeting him if we didn't have kids. The only reason I am going to meet him is to get some sense of who this guy is. If I didn't have kids, I would've been outta Dodge a long time ago.
About her saying it's in the 'beginning' stages - don't believe a word they say. If she's introduced him to the kids I doubt it's in that stage. But in any case, it's good luck to him nonetheless. Let him figure this out lol. His personal situation sounds kinda terrible too so don't know how emotionally healthy he is. But not for me to judge or worry about. All I know is that if two emotionally unhealthy people get together, ain't leading to nothing good. If he is emotionally healthy, he should be able to spot that my exW ain't his cup of tea.
But again, not by battle to fight. I am just out and I plan on staying wayyyyy the hell out.
