Ill be completely honest. I would have killed for even a fraction of this type of response, rather than all the blame and lack of self awareness, that being said all you can do is validate the feelings but not contradict anything. Im sure a lot of this email is a rewritten version of actual events and a type of recency bias but in the end you have to keep doing whats best for yourself and maybe everything else will fall into place one way or snother. Theres still a high likelihood of an affair as an affair makes its easier to compare a short term fling and exaggerate the differences, so keep this in mind
