You spent *months* befriending me, and exchanging personal secrets. I know you don't want anything serious, but I trusted that you were my friend. I didn't want anything serious with you either - which is why I decided to go for it, even though I usually pursue long term, monogamous relationships. You put so much effort into getting into my head and getting to know me, but as soon as things started getting sexual, you withdrew and won't even talk to me for days after. I know it's probably something going on with you instead of it being me - but I told you I'm extra sensitive to rejection and I keep wondering what I did to offend you. I didn't think that was all you wanted from me, or that I was so disposable to you. I don't want to think I wasted my time on someone who would lie to me and use me like that - but what other conclusion is there?
