Sounds like this site is attempting to help people justify cheating. Put nope, Polyamory and cheating are polar opposites! I did meet someone who was in an open marriage who briefly used Ashley Madison to find partners. She was open to her spouse but those she met up with weren’t. She didn’t know about Polyamory or how to meet other poly people at the time. Once she learned the vocabulary and found better sites (I met her on okc) she stopped using AM.
