friendship can be remained forever?

Actually i am so curious about this friendship..i dont believe that friendship can be remained forever..Why i always facing this problems in my life? HATE IT...just like be abandoned and betrayed....
When the other join in, i can see the friendship start changing..i really didt think too much, i can feel it,u know....i just like being foolish by someone,so stupid...haiz
U know perli by friend is not a happy thing, i just like to share with each other, not the type to show off or fighting in materialistic...Right now, i also feel that i am being far from them, i dunno what topic they are talking..
When doing work, they didt take it in serious, everything dun care..For me, when is the time to play i will enjoy it; when is the time to do work i will be serious...that is me...
When asking people something, please ask in manners way...if u want to ask then u must listen to that person...but the person fight back what u talk, is rude..if u dun believe what i say then better dun ask me,am i right?
what the hell? Haiz......being stress, u know?
What is the inner of friendship?
When i am not happy i can share with; when i need help, they are beside me;
Last time we share the problems together but now nomore already..all become materialistic and realisitc...
