Zero upsides to it as it stands today.
Zero. For the guy. Its a one sided contract only he is held to.
For women its great. Even if it fails they win big.
I’ve seen too many decent guys get ruined financially and emotionally, all because their wives got bored with them.
I’m 59, and consider myself one of the last Old School Bachelors.
I’m polite and kind to females, and I do have a lot of respect for the few couples I know who seem genuinely devoted to each other.
But you’re not talking about anyone under the age of 50. And who knows what goes on between two people when no one else is watching.
