Relationships don't last forever?

i am someone who can't handle anything ending, i can't deal with the idea that nothing is forever. so i am a disaster when it comes to relationships ending. even if the guy is a jerk%26lt; i fight to keep the relationship. i don't understand it and i don't cope with breakups. how can i start dealing with impermanence? how do i fix my way of thinking?Relationships don't last forever?
don't give all for the relationship, u must focus bout ur self, love ur self, it's more powerful, don't be needy to them... and not all guys are jerk, there are more of them will love u, with all of u. i know, u'll find it someday, time will tell u.... u can do it, be patience..
