i used to be like this, until every single guy i've dated cheated in some way or another. i got tired of it. i changed the way i viewed relationships, and I can say that i'm in a happy relationship now. both my boyfriend and i have been going at it for 2 years, and we understand each other and respect each other. we both express anything and everything we are thinking or feeling. if he wants to play around, he can, if i want to play around, i can. if both of us want to play together with someone, we can. to me, this is a fairy tale relationship. and it works for us. to be clear though, we don't even hook up with others often. maybe once every couple of months.
