Yes ! I need a time for forgeting all about him who even I love ,
I don't know why sometimes I feel so love him so much and hate him too. 
I know he not love me again after him got a new girlfriend (of course lehh I happy to him) but don't know why this heart say differnt . 
This feel like this song Song by AVRIL LAVIGNE with tittle is Happy Ending.

"My Happy Ending"
So much for my happy ending
Oh oh, oh oh, oh oh...
 
Let's talk this over
It's not like we're dead
 Was it something I did?
 Was it something You said?
 Don't leave me hanging
 In a city so dead
 Held up so high
 On such a breakable thread
 
You were all the things I thought I knew
And I thought we could be
 
[Chorus:]
You were everything, everything that I wanted
 We were meant to be, supposed to be, but we lost it
 And all of the memories, so close to me, just fade away
 All this time you were pretending
 So much for my happy ending
 Oh oh, oh oh, oh oh...
 
You've got your dumb friends
I know what they say
 They tell you I'm difficult
 But so are they
 But they don't know me
 Do they even know you?
 All the things you hide from me
 All the shit that you do [CD version]
 All the stuff that you do [radio edited version]
 
You were all the things I thought I knew
And I thought we could be
 
[Chorus]
It's nice to know that you were there
Thanks for acting like you cared
 And making me feel like I was the only one
 It's nice to know we had it all
 Thanks for watching as I fall
 And letting me know we were done
 
[Chorus x2]
[x2]
Oh oh, oh oh, oh oh...
 So much for my happy ending
 
Oh oh, oh oh, oh oh...
