Welcome to our forum.
Sorry to hear about your pending divorce. Some partners take the "polyamorous news" fairly well, but there's no way to control (or predict) that. Anyway, I'm glad you could join us on Polyamory.com, and hope you find some new friends here. There is much to post and read.
Wishing you well in your new poly life,
Love means never having to say, "Put down that meat cleaver!"
