Not sure if you should even contact OW. OThers can chime in but if YOU contact her, it elevates her importance in your life (IN HER MIND). I would see if she contacts you. OW in my stitch contacted me this past weekend and I FELT SO GLAD THAT I never went through with calling her. Now, she and my husband look like highschoolers playing these games.
However, if talking to OW in your case is part of your exposure then nevermind what I wrote above. Just wanted to give you another perspective on YOU contacting the OW.
Remember at the end of the day you always want to be able to hold your head high and say that you did the RIGHT thing at all times.
