(I always like to see updates in other threads, so...)
I actually met TJ in person a few months ago, after everything had blown over. She introduced herself, shook my hand, although she might have been overcompensating a little. Alcohol also may have had something to do with the friendliness. DK ended up being the most uncomfortable, I think, but it was okay.
WK and I got married, and moved to the states. Which was a little while coming, but it means that DK and I are longer distance now after a great summer. Fingers crossed any new metamours are more okay with me, although I suppose distance should make me less threatening? Ahhh.
Good luck to any of those coming to my threat with metamour problems! I think the best thing you can do is be supportive, yet still manage to voice your own interests and views. Hooh. I think it gets easier.
