First, there is NO correct time to "get over" your grief. The so called societal one year limit is preposterous.  In former times and cultures,women obeyed the prevailing custom of wearing black until the first year was officially over. They withdrew from society and basically "died" along with the deceased. Now we have work mandates. Three days off for the death of a loved one and back to work again! Three days!!

There is nothing more earth shattering than finding that your relationship and partner are not what you thought they were.  Loss of trust on the one hand, and guilt on the other, are the primary painful feelings in this situation. Healing from infidelity is one of the most challenging issues a couple must face. But, as they say, conflict is growth waiting to happen.

"You shouldn’t feel that way!"  Really? Why not? So often parents or partners are annoyed by your feelings, which only makes you feel worse. They are discounting your emotions because they don’t want to deal with the issue at hand.

Think of your life as a movie.  You are the star and you see the supporting actors. The script was written partly by the screenplay you landed in, and partly written by you. Yes, you. 

I see this so much in my office, couples wanting to re-hash a week old argument and wanting me to judge who’s right. Detail by detail they correct each other, exactly who said what, who did what first, as if each admitted detail is a score toward the finish line. But nobody really gets anywhere because there are no winners in an argument between partners.
