trust vs betrayal

i'm pretty much f*cked up rite now. why? cos the person u cared the most had betrayed u. how can u trust a person when the person itself broke the spell? the only thing needed is trust and that trust has been broken in just a few months of 'leaving'. knowing the word trust for 8 years is not worth it.. and it really breaks my heart knowing that serious betrayal. shud that person deserve a second chance? i'm not sure yet.. cos now my heart is too cold to decide~~
