"Relationships"

So last year I dated this boy who i fell in love with seems perfect right? WRONG there's this girl who had to go and ruin everything shes a complete BITCH! So lets start in the beginning sophomore year I met this nice boy and we became good friends a few months later we started to date it was a good relationship but summer broke us up (as most relationships during summer end) we stayed good friends until said "bitch" showed up. See this boy couldn't decide which one of us he wanted so as boys tend to do he picked the easy girl over the sweet, beautiful, caring girl (me). This is when the nice sweet boy started to become less nice and sweet. The two stared dating and yes I was pissed because this boy gave the impression he liked me (which he did) but started to date the bitch because he got in her pants within the first two weeks of their relationship. Well of course this "relationship" only lasted one month and guess who came crawling back to me. So me and this boy started to date again and all was well but I didn't realize this wasn't the same sweet guy from sophomore year. Due to him dating the bitch he became one himself and broke my heart for what reason? to this day I don't know but we lasted longer than him and the bitch but there is still drama one year later seems like the bitch can't accept the fact that he liked me better and always will.
