Distraught, let me share a little bit of detail about my story.
EA #1 was with an ex. We had had a relationship that ended on ambivalent terms and we never really "got over each other." In around June or July of '07, while my BH and I were engaged to be married, he discovered inappropriate text messages between the OM and myself rhapsodizing about our former relationship and how we missed each other, we considered each other "unforgettable," etc. Now, obviously, there was nothing wrong with having those feelings---even as a remorseful WS I believe that to be true. I would suspect that a lot of people have fond memories about exes, especially if nothing specifically negative happened to cause the end of the relationship. BUT---I obviously should not have been engaged to be married if I wasn't over him, and even if I was actually over him and it was "foggy thinking" to romanticize the past, I should NEVER have been having that kind of dialogue with him while in a relationship with someone else.
My BH (then-betrayed fiance) and I ignored this huge red flag and got married. I was like you: mostly NC with the OM except for work-related issues (we were coworkers also). OM and I didn't talk more than a handful of times in over 3 years, and nothing of a really personal nature.
This past September, I had a profound experience that triggered unresolved feelings for the OM. I texted him, the EA was back on immediately, and within a matter of a week or two had become a PA that lasted for over 5 months, culminating in D-day of 3/6/10.
This could be interpreted several ways. In my fog during the affair, I believed I was in love with the OM. He certainly claimed to be in love with me. He claimed that he had never gotten over me, wished we'd had a second chance, maybe we'd have one now, etc. And I parroted these words right back. All things being equal, I believed that the OM and I had just as good a chance of having a happy relationship as I did with my BH.
However. In the excitement and fantasy of the affair, I overlooked so many character flaws in the OM that it's funny (in a sick way). First and foremost, he was willing to have an affair with a married woman. Obviously I'm no better---but what did that say about him? What did that say about how much he VALUES marriage, and commitment, and relationships, and honesty? There are a lot of other issues with him too, that I excused and glossed over and romanticized because I was too busy being excited that this POS "chose" me again. (Obviously I don't value myself very much if that was enough to get me to kill my marriage.)
Workplace affairs (and even dating in the workplace) are such a bad idea, IMHO, because it is so hard---especially in this day and age---to quit the job if things don't work out. Yes, I should have had the strength within myself to stay away from him. Yes, I was going to send the September text message whether both of us still worked there or not. But it made it much, MUCH easier to take things to the next level because it was so easy to see each other every day if we wanted to. I really believe that "out of sight, out of mind" is true to some extent. Daily contact (even the visual kind) keeps things alive. Ease of access makes it easier to choose the wrong decision. Seeing the OM kept my feelings cloudy toward my husband and my marriage, and I'd be willing to bet that it's doing the same to you.
The really fucked up thing in my case is that NOW I will have an ex-OM and an ex-husband at work with me! What a tangled web we weave.
