I know the differnce between open and cheating. When you lie, sneak, hide, and flat out do whatever you want with and whenever you want while married...even "open" with no reguard to your realatonship it is cheating. When you replace one person for another..that is a not poly that a seiral cheater.
reality was he wanted me mono but he didnt have to be. He coul do whatever he wanted as long as I didn't do the same. Sorry, i don't buy into that illogical blame throwing game. He knew was open intailed. We had a contract before marriage . he choose his actions. I simply with held my end of the deal...you break the rules. It is a deal breaker for me......He did. I left. Was pretty cut and dry to me.
