If youre married, why hobby ? You know whats at risk. If you get caught youre going to get skinned in divorce court. Soon as your soon to be ex wifes attorney mentions you were cheating on her with call girls, youre screwed.
Kids aren't going to be too happy I'd imagine stepping out on mom with professionals.
Even your job may not be safe, if you work for some snobby judgmental types. They'll burn you down without a second thought despite years of loyal hard work. I'm sure they won't come out and directly can you, they will feel the need to play those games upper management likes to play. But that will be the root cause.
Maybe you own your own business but guess what your going to lose in the divorce.
So why not get divorced now, while its still somewhat on your terms, then you can play without worry ?
Divorce law is draconian I know. but if you initiate it, you can make preparations ahead of time, soften the blow as it were.
