I don't know why or how but I ended up marrying a boyfriend who I knew had had sex with my mother years before. He and I had dated, then split up for 3 years, then sort of fell back into a relationship. It was during the split that he took her out for a couple of dates.
She doesn't know I know.
I have divorced this man now for other reasons related to his inability to keep faithful.
I am obviously never going to tell anyone IRL, but I'm now metaphorically beating myself with a stick as the signs of his infidelity and sleaziness were right there at the beginning. And I wasted so much time on him.
How to let this regret go and stop looking back?
