Thanks for the update, as always. So your take on people who leave their relationship (was sis' friend married?) for an A is that it can happen to anyone and you don't judge? I'm surprised. I don't know that I could be so generous. What makes you think sis' friend is not more prone to it than the average person?
What I perceive is that both of you see the hurdles to a R, but are very attracted to each other at the same time, so you're willing to overlook them. I think that handling an eventual break-up would be more difficult than you anticipate because you'd have a messenger in between and multiple opportunities to meet. You'd run into each other's new significant others. And if you eventually R with WW, then it will be very awkward to meet her with your sis. I surely wouldn't want my WW's ex around if we R.
I sound skeptical, but I want is to give you an external perspective, from the little that I know. I also don't believe it will have any effect, because I know how attraction feels like.
