My husband had two inappropriate attachments about 21 years ago. There was an overlap, one started with a co-worker in 1998 and the other on started around 2001 with a fellow graduate student. The first attachment lasted for 8 years and the second for 4 to 5 years. His last one had more of the characteristics of and emotional affair via texting. With the first one it was limited to contact at the office. With the second one it did progress to a lunch and having opportunities to being alone on campus. The third one started May, 2018 and ended in the middle of July. I confronted him about this one when he wanted her to try out to be a lead singer, which meant them being alone in the music room. She was neighbor. My question is he felt that having a sexual relationship with any of them would have been wrong; I think he was afraid to take any of them to a sexual level because at times he would have problems maintaining an erection. So, what keeps an emotional affair from becoming sexual? These women were all about 10 years his junior an 15 years my junior.
