I feel the same way you do about the poor stats on reconciliation. It seems especially worse when it's the wife who has betrayed the husband in an affair context. If I thought there was a decent chance, I'd be more open to it, but from what I'm seeing the rarity will just feed paranoia.
I don't know what I'll REALLY do myself if/when the time to discuss reconciliation comes. I'd like to think I won't entertain it.
Please don't take this as a vote for what you should do. Just me sharing that I wonder the same things.
