I think it can be a common event for people to go back and think about it all.
My first husband left me for his mistress and married her. We had a daughter so I will be stuck having to deal with him , well forever altho not nearly as much as she’s now 27.
I have had a few rounds of reliving it over the years, I also remarried and am very happy.
What went wrong in my first marriage ??? It really boiled down to and my ex finally admitted.. my father fought a long 2 year battle against Leukemia and I did spend a lot of time with him at the hospital , he would be there 6-8 weeks Home 2-3 and back again. My husband the “ poor thing felt neglected “
When these feelings come up, acknowledge them, feel them, remind yourself you brought an amazing child into the world and remind yourself your in a loving relationship now
