Theft by deception

I've been trying to parse out my feelings. One of them being outrage. It occurred to me that a crime of sorts was perpetrated against me and many of the rest of us... I know now he was having a r/s that probably overlapped me for a year. We were in a grey area by then but I specifically told him that I wanted to know if he met someone and started another r/s. Of course, he wasn't going to do that and risk losing me as supply as I know now. Duh. So, he received value for his deception - sex, companionship, advice, etc. Anyway, it just pisses me off badly and it should be a prosecutorial offense!
