I'm not talking about divorced people, but about the fact that raising other people's children when you don't have your own is a behavior typical of a cuckold. Unless it's a widow, then it can be understood. And even then, just in case, it's worth checking the death certificate of her husband.

And according to that logic, if you get together with a guy/girl who isn't a virgin, then you're a cuckold. BECAUSE THIS PERSON HAD SOMEONE BEFORE YOU.
