Did you ever wonder why at this time in your life this happened?
For me--the OW picked just the "right" time to come into H's life.
In the nearly 20 years that I have known H, this period has been the most depressing for him. He was at the lowest point in his life and hated himself for many reasons. This is the most stressful period we have ever been in as well.
In pops OW to make it all better. OW was an ex girlfriend from before our marriage. He had not talked to her in 20 years. She reached out to him via an email and BAM thats all it took. He latched on to her immediately and she had all the answers to make it all better. If it were just any woman--he wouldn't have latched on so strongly. But, it was his true "friend". I know its been discussed on here that it could be any woman--but I don't think that's true in my case. It had to be her in particular for him.
I really feel if she had come back in at any earlier point he wouldn't have responded back to her.
Its just ironic that she would have picked "now" to come back in to his life.
