My best friend's husband had an affair for 8 months with his longtime friend. Apparently he is refusing to block her (the OW) after she asked stating the friendship is of importance given the length of time they have been friends, but has offered an open phone policy and proof of no contact. I don't think it's unreasonable for her to ask that he cut contact/block forever? I guess this is triggering for me having gone through something similar and in my case; my (now ex) husband just got sneakier about his shady ways.
