Regardless of her age, the idea that if your husband cheats, its the other woman's fault has always seemed an extremely non-productive one to me. Or vice versa, of course if your wife cheats, time to get my gun.... It is just so easy to blame the other party, hate the other party, and in so many cases, attack the other party in some real or imagined way. But we are doing reality orientation counseling here when we remind Maria that here are some problems, NOT caused by someone else, they're caused by a flaw in this person she's attached to. Fix it or leave it, or it won't get better. If you're going to accept it, don't call the other party and make threats.
