Sorry about the break-up, Mojo.

Re: polyamory, I have a friend who got out of a marriage to a p/a LD guy a few years ago who tried that. I think she was intoxicated by the freedom after finally getting rid of him. She was in a semi-LT open R, with both new BF and her having other partners. She ended up in love with new BF and had her heart broken when he moved on to greener pastures.

She's now doing her version of the cottage in the country, and back to serial monogamy.
