I forgot to add that I believe he is having an EA with his friend's best friend. He "mis-texted" me on a phone IM app. It was a couple of weeks ago, and I'm thinking it very well may have been intentional. The series went like this:
"I know you are paying attention to class, but I just wanted you to know how truly blessed and lucky I feel to have you in my life. You have given me new purpose in life and made me happier than I have ever been. I love you!"
He then "realized" that he im'd it to me instead of her. He said:
"Don't get me wrong. The love I have for you is as a friend and the mother of my children."
"Let's stop the bs and get along."
"Our kids don't deserve this."
"Wow. That's one for the autocorrect website. So not what I meant to type."
Yeah. He totally tried to blame it on autocorrect. Riiiiiight.
My response was:
"I knew it. At least now I have a concrete answer."
He denied it at first, trying to maintain that it was autocorrect's fault. He really must think I'm an idiot. He finally admitted that it was for her. He claims that there is nothing going on, and that they are simply helping each other through a tough time (she and her husband are separated too - big surprise).
Before I stopped obsessing over his phone records, I noticed that he was calling her immediately after he and I had some sort of interaction. In my book, when someone is talking to an outsider consistently about their messed up marriage, that is most likely an EA. What do y'all think?
