OUCH. That would sting and burn like hell. Only you can know whether you have it in your heart to forgive and move forward. Trust may be very difficult after this. That's a long-term affair. Your family should have told you. That's appalling. I don't know if I personally could move forward after that. A 9-10 year long affair and in the same bed would be unforgivable for me. I am soooo sorry. I can't even imagine what you're going through right now. ((((((((Hugs))))))))
