falling in love while in love

Hey me again with a problem that maybe not alot of you can't relate to but I really just need to talk about it.Ok so I am going out with this guy he is my boyfriend many of you may have seen him picking me up from harlem live but before him I was going out with this guy named harold understand this to me he was the love of my life he was very thing a girl could want rememder "love is blind".So after we broke up (for reason that will not be named) he changed I saw him for the asshole he is he was just so fucked up sorry to say but he love to make fun of kids in our school that have special needs I felt horrible but I couldn't bring myself to hate him I still can't hate him( sometimes I think that if he were to tell me he still love me I would go back out with him sad isn't it).But I just join the talent show and he happen to be performing now I just join the talent show to be with my friends and I am working back stage so I thought that I would be seeing him much wrong! so wrong not only did he played one of my favorite love/break up song he made me cry and start thinking about all of the happy times we had together and it like he knows what he is do because he picked the perfect timing just when me and my boyfriend got in to a fight and now the only thing I want to do is ruin my happy life/relationship (because I am happy) to just see if he will cares that I left my boyfriend for him even though I don't it before (but sometimes I do think that I just looking for an excuse to break up with my boyfriend )which according to alot my close friends I should break up with him because I deserve better I really don't know what to do but I have no time for boy trouble I have to worry about how I going to tell my mother I fail one class that I always get 85 and 90 in and how I got a 65 in spanish my native langauge.Laterz
