Nah, just to clarify, I don't think it's is a bad thing to keep tabs on the MLC'er and see just how great that new-found happiness looks on them (snarky, I know, but happiness, pffft!), some people aren't able to stop at just that. And many times, especially early on, that kind of digging and snooping will burn like acid when the LBS sees these jerks "living it up" as they pretend the first year or 2 into this crap. But, maybe that pain is what they need to feel to get on with their own lives. At some point, it's going to have to happen for them, or they really will be left behind.
I know I was really wounded when xh walked away, but then I saw what he was walking away to. It was a travesty, in my honest opinion. I wasn't sure if I should be offended, disgusted, or overjoyed that this OW (yeah, symptom, whatever) he ran to be with was so far beneath me in every way possible. Now, after almost 18 months, I see this as the karma everyone jilted person clamors for. Two broken, adulterous liars in a relationship that wrecked both of their "awful" marriages and now they are stuck with each other for all eternity. In my book, karma doesn't get much b!tc#ier or better than that. You cross the line, you get what you deserve. And, as for this blissful happiness, now watching and peeking from a distance is quite satisfying...and letting him do the same in return is even better because mine here in good old reality is genuine, and his, well, that remains to be seen.
