advice quickly please!

hey...this isn't the most depressing thing...but i didn't think it was happy enought to put in love n romance..so heres the thing...
i just read a few quotes sayin ' never to let the one you love go' and... am thinking i shud maybe finish my guy when i see him tomz...but i still love him soo much...and i'm confused about the way he feels about me...when ever we come near to splitting he always convinces me in every way possoble, but as time goes on...i'm really unhappy again. i don't want to go in 2 what he does and everything, but, the bottom line is, i'm alot lot more depressed and started doin silly things, and now hez not happy, and i have a feeling its 2 do with me. but however much he upsets me, i still love him more than any1 because hetrys his best to help me and understand even thought he can't, but no one else ever tried to... ok am rambaling on abit now.. so just... i dno what my hearts telling me to do...part of me says in the long run i'l be happier alone, but then other parts saying hez something really special, so giv him a chance and it'l be ok...
so am just really confused??? please any suggestions!
