Empowered, it appears that you have a handle on the communication needed in any relationship. Your BF doesn't, it seems. I've stated on other responses that if communication isn't clear and open there will likely be problems in other aspects of a relationship. What he is doing I say is cheating. Dictionary definition is doing something, in this instance having sex with others, without you knowing or approving and is definitely cheating. Cheating often leads to anger and separation. Having sex with others, with full knowledge, is not cheating and I also say is not what some religious persons say is adultery. If, after attempting to communicate your feelings and desires you get nowhere and the cheating continues I strongly suggest LEAVE HIM. It sounds like you are a good person to be with some guy who appreciates you and is very open to honest communication.
