The person has three choices
A) Talk about it. Suggest counselling.
B) Put up with it
C)Divorce
D) Flirt with and shag someone else is not a great option. It’s abuse as you are risking your spouses mental and physical health. Some STDs are life changing. Cheating can cause PTSD in some victims. That’s abuse in my opinion.
Cheating is not cool, nor sexy, or attractive.
If you eventually split and divorce at some point you will be on a date and get asked: did you cheat on your ex? What’s your response A) yes but…. (Insert pathetic excuse). Then what happens?
B) No - and you continue being the liar you were in your marriage.
Cheats have a but in their fidelity. I am faithful but not if my spouse won’t find out. I am faithful but if my spouse gains weight it’s okay to rub genitals with another. I am faithful but if my spouse let themself go it’s okay to risk their sexual health.
I am faithful for ME. My husband is annoying. But nothing he does or doesn’t do can make me cheat. I stood in front of friends and family and made vows. Those were my words, given freely. Who am I if my vows mean nothing. If my word is meaningless. I want to like the lady I see in the mirror. So I stand by my word . I am faithful for me. My husband is collateral damage to my daily choice.
Cheating is easy any loser can cheat. Being faithful or ending things correctly says a lot more about someone.
