Thanks for the response - I totally needed to hear what you said.
I've been speaking to a lawyer. Engaged one formally last Friday - he warned that it looks like WH has already taken legal advice and is shaping up for a fight. Which will take 6-9 months and cost approx £60K. I am terrified. We are seeing a mediator for the first time today - I am really really petrified. I am all alone here - WH has his family advising him on what to do, who to call. Barely slept last night.
You're the first person to tell me that OW is creep. Thanks for that - it's made me so happy! Everyone's been pursing their lips and saying '"Ah well, she's single, she didn't make any promises to you..." I totally get that it's my scummy WH that's broken my heart and spat on our shared history, but she's not innocent! My own father told me she was innocent, and my M-i-l has disappointed me so so much by refusing to judge her. I thought M-i-l and I were close - true colours showing now! She's just waiting to meet her now. I feel doubly betrayed - by WH and his family's response to the OW situation.
I should mention that both his parents cheated. They know we know about his father's affair but it was never mentioned, and his mother doesn't know we know about hers. WH always told me he would never do what they did -
