I'm so sorry to read your update. I've been through this and I acutely remember being in exactly the stage that you're in now. I don't know how they can throw it all away for someone they just met. I guess they'd been on auto pilot or unhappy for a long time without communicating their true feelings. Marriages can overcome infidelity but it's a lot harder when you're faced with divorce. If it's any consolation, my husband wanted an immediate divorce and here we are, two years later, still not divorced (but separated and his affair partner lives with him). You can't exactly anticipate what will happen but life will never be the same. It takes a while just to absorb the shock.
It just boggles my mind how she can throw away the marraige for someone she just met. My guess is the new fire, adventure she feels, the excitement, etc. My WW wants a divorce and she wanted it quick, now I know why - she wants to spend time with this OM. The messed up part is she took my D school shopping yesterday and I guess the OM and his kid was with them. Before I knew about the PA, I agreed to pick up my D 20 minutes away - come to find out when I picked my D up the OM and his kid was across the street at a store and WW would go back to be with them afterwards. This is so messed up. Life isn't the same, even if down the road she wanted to reconcile - I dont think I can after she lied to my face multiple times about the OM especially laying in bed with him every night. It's the ultimate betrayal for me.
This was definitely a curve ball. I had a sense of the PA but didnt want to believe it. I will try to continute to GAL, care for D and try to enjoy life as much as I can. Thanks all.
