Hi Mitch.
I know exactly what you are going thru b/c my partner txted me pics of him & another woman in bed after we got into an argument & I broke up with him briefy.

You are not responsible for her cheating. She has to take accountability for her own actions. IDK what happened in your marriage but I always believe it is best to leave a situation before starting another. She was wrong for rubbing it in your face & wants you to feel bad about it. Try not to get angry & if you catch yourself doing so, walk away & do something you enjoy. Tit for tat is the wrong thing to do & will further damage your relationship, mental health & spirit. If she is truly apologetic and sorry, try counseling & working on your problems.

Please let us know what happened.
