Out of nowhere, my XH announced that he wasnt happy, hadnt loved me for some time and left. I had no idea that he was contacting OW at this point and was totally shocked and devastated. We talked for hours and he came back, left again after 6 weeks.
unknown to me at the time, my XH was having an EA. He was sharing everything with his mates wife, telling her all his feelings, discussing our marriage , telling her all his/our problems that I wasnt even aware of. She in turn, said that he could provide her with the emotional support that her husband couldnt. He sent her "motivational" emails, while pretending to me that he was trying to make our marriage work. his phone was glued to his side and he set up secret email addresses.
XH deleted all texts/emails, he didnt tell me that he was in contact with her. He started finding excuses to spend time with her and talked about her incessantly and also started to run his friend down.
It ended our marriage as he was adament that he no longer loved me, so I divorced him. OW is still with her H and he hangs around with both of them and is still contacting OW obsessively afaik (his family have told me).
An Emotional Affair is very dangerous, because it is all built on fantasy. it is all faceless behind a screen, they can say what they want, that they probably wouldnt say face to face. XH was no flirt, but he flirted with OW on facebook and email. All of his day was taken up with contacting her and thinking about her and not about his wife and then 3yo DD.
It is a huge betrayal of trust and not something that everybody can get over
