pulling on my heartstrings

ok, i know i shouldn't be saying this but i officially like this lad.... again. i know my friends are going to kill me but i cant help it! they know i dont listen so theres no point in telling me what im doing wrong but never mind il learn.... eventually. the only thing is is that u thought i had learnt my lesson before and now i like him again. i am completely confused! you know i sometimes think that there is someone inside my head just playing with my emotions just to annoy me. honest to go i think i am missing a part of my brain that makes me learn my lesson with this lad, i need my head sorting out, now! and i dont know what to do either, listen to my friends and just try to get over him or let things run their course and sort themselves out.
