What A Joke
I think it’s hilarious that this ends with them still happily married. He cheated on you. If he was broke, you would be happily divorced and he would be a loser who didn’t deserve you. Just because this guy had money you will forgive and forget.
That is just ridiculous. What else will he be able to get away with because he has money? My guess is that he didn’t stop cheating. You just stopped looking and started spending his money to make yourself feel better. There is more to life than this. Maybe you should think about something other than your bank account.
