How did you cope? I've been with STBXH for 29 years, married for 19. I found out over the course of the past few weeks that he has probably never been faithful to me for all that time.
I'm wondering if this is what an existential crisis is! Every memory, event in all that time now seems like it doesn't exist, I don't know who he was, who I am. it's really destabilising.
I am seeing a counsellor but I would so love to hear from anyone else who has been through this - what helped (I am assuming time is a big one)?
