I would also say that, from this experience, I bet it's not going to be as *exciting* once they know you know. It could die out just b/c of that. I would venture to say that a lot of EA's continue and just happen in general b/c of the "honeymoon" phase & the excitement, etc. that is going on.
{IC nodding his head in agreement} I know once I found out about wife and OM, that pretty much ended it. Who knows, maybe it was ending naturally but my guess is that the excitement had worn off once it was exposed.
