Whatever...i am confused..

What do u do when you start hating somebody?? like a fren who was very near to you for a while??? i mean i am a lot confused with kind of relationships i make with people.. everyone is just so special for me in their own sense..... hmm...and i just cant accept the fact that relationships esp with friends can change with time. They become better or worse. I have seen many getting better all the time but what hurts is when things dont go good with some anymore. Should I start avoiding them for a while so that it gives time for it to settle down... or should i just give them what i am getting from them so that they realise that it hurts. well i am totally confused. but then i think need not worry as i have too many frens in my list who care for me and are always ready when i need them and want to talk to... but then that does'nt make any sense at all... coz everyone is as important as anyone... hmm.. But then the problem is why when i did not do anything so rude that i deserve such a treatment based on assumptions made by them. well... So i suppose i'll let things lie as they are going and just get along.... and just chill..!!!
