Love?

Hey! im extra new to this but imma just use it as a venting thing. So the first topic i picked was Love. LOVE=PAIN is my thoughts but hey, i could be wrong. Here's my situation. A guy i thought was cute started talking to me and we became friends, little did i know my cousin was what he wanted. He texted me and talked to me outside of school yet inside of school he acted like i didnt exsist, painful to me because i just looked pass that. Love was blinding what i should of seen. I've been used so many times in the past, mainly to get to another person, and i thought i would know if it was happening again. I WAS WRONG. I fell for his eyes and looks and how he talked to me, ignoring the fact that he asked about my cousin a lot. So in the my mind clicked, i cried for hours no lie. the bad part about it is that he has a girlfriend yet he's STILL tryna talk to my cousin and other girls in our school. So when i see him either alone or with some girl, i feel a lot of things angry, sad, depressed for not seeing clearly, and all of those because deep down i know i would give him a chance if he asked. Now i have even MORE trust issues... All because i let me heart fool me! You guys might think love is all Sweet and sugar but love hurts. PS: I MADE THAT PICTURE.
