3 year old EA - where do I go from here?

[Matrix5]

One thing I didn't mention was the charterer and the nature of OM. We have been sitting 3ft apart from each other for the last 10 years. I consider him more than a co-worker. He's a friend of mine. From a charterer standpoint, if he were a dog, I'd describe him as a half chiawawa for his nervousness and paranoia with regards to certain things, and half golden retriever, for his fun, laughing, loving, and goofy character - which is something I think my wife is attracted (I'm more of an introvert as mentioned in the OP). Yet, that's a guy that freaks out whenever W tells him I know they have been talking, afraid he'd lose his job and/or his family over this A.

Meanwhile he sits right next to me, and every time he picks up his cellphone to answer a text, I can't help but wonder if it's my W on the other side of that conversation. It would have been easier had he been in a different department or different part of the building. But the guys sits right next to me, and to make matter worse, we report to the same boss. If the A was to ever be validated and exploded, I would not be able to sit next to the guy. What do I do then? Let my personal life get into my professional life? Quick my job over this? I like what I do, I get paid well, and have been with this company a lot longer than he has.

I feel like turning around to him and ask him point blank: Are you screwing my W?!?! But I know nothing good will come out of such question.
