This nonsense about wayward spouses running off into the sunset having great lives after divorce is just that... nonsense...
Freinds with benefits and casual sex crashes and burns... sometimes unpleasantly with an STD
Remarry? Did you know the divorce rate for second marriages is much HIGHER than the first marriage of 50%? Yes HIGHER.. that's because these people took their baggage, their scars, miseducation, and myths about marriage right into a new one instead of staying and doing the work to learn how marriages survive...
The long term success rates for affair couples is less than 1%
Staying and doing the work to understand what commitment means and how to keep it alive is the best game in town... If you aren't at that table you are eating fast food and doomed for an ill life long term
