I just read your thread. I understand what you are going through. I've been Piecing for 7 months and to say that it's been difficult is definitely an understatement. To this day I still feel anger and resentment but it's getting easier with each passing day. Your question about how long it takes to get over OP? I read on another site that it takes a minimum of 6 months if there is no further contact with OP. In my H's case he continued contact for a year after the PA ended and I think he's still dealing with effects of withdrawal. I just want you to prepare yourself for the possibility of it taking longer than 3 months. It's a very positive sign that your H is getting IC to help him deal with his issues and the issues that will come up during the Piecing process. Take it slowly. It's a long road ahead but you're doing great!
