I really hope to have a relation with her... but the problem is she can't forget her x boyfriend... and she told me that she will always suddenly miss him... wat can I do... to help her forget her x boyfriend? They had already breakup for a few months... recently, the x boyfriend will sms her... it made the girl had a cool feeling towards me... what can I do to make her forget her x boyfriend... I really don't hope to miss tis good girl...

You can't force her feelings,she needs to heal from her breakup. Any relationship she tries before having healed will be a rebound and you don't want to be that guy.

It means I nid to wait by doing nothing?

It means you let her heal and step back and get on with your own life. There are no guarantees that she'll want to be with you once she's over the ex.

Oh... now I have fully understanding what you means... erm...

Yes, leave her alone, and do your own thing, because as long as she is dealing with the ex, she is not available to you, nor do you want to be under those circumstances.

Text/chat is hard to understand. And against the rules by the way.
