A hypothetical situation, we don't often get such a clear cut choice 😆
If you did, man one was married for a decade or so, has a nice realtionship with his ex, sees his kids EOW and school holidays. Pays what he should. Everything rubs along mostly, with the odd disagreement about time and parenting methods. They spend family occasions together.
Or single man, enjoys life. Nights out, holidays, sport. His time and money is his own. Has never had a real realtionship and possibly never properly grown up or had any real responsibilities.
Both in their mid 40s.
