Listen hon, between my last boyfriend and my current boyfriend I was basically exactly how you were. I've had a few guys to fool around with in between but basically all they told me when I asked them if they wanted to actually date was that I was more like a sister then a girlfriend. I know EXACTLY how you feel, but after almost 7 months of being single and just yanno, shopping around (LOL) I found the most amazing guy who loves me to death. It just takes time, you're still very young and you've got so many options around you! Open up your life to new experiences and maybe you'll meet new people who don't have that 'sister' view of you? I dunno, but good luck babe and really, one guy isn't worth much..especially if he doesn't seem to give a shit. (That girl's probably a dumbass too)
