MJDG, Sorry you here, so are you saving your marriage for beliefs or because you truly LOVE your wife. Some people are not meant to be together some are. Take this time to get to know yourself again besides no sex no affection why did you have an affair.
I can tell you why I had a EA I needed to know if I truly loved my W and when I went to meet I froze I couldn't move forward I wanted to call my W and tell her am coming right back but I stood quite till finally it came out that it was just a EA I couldn't move forward with SEX.
It looks like you in a hard place maybe start off as friends again,dating ect if I had a chance again God knows I would but my stitch a little different W didn't just walk away from me but she did to our kids and said some pretty hurtful things that now my d9 and s8 are in some serious therapy. But as I say to everyone a day at a time that's all we LBS can do.
