I was betrayed by my g.f but she came back to my life after 2 long years.. but she is changed now the charm of my love is not the same I tried my level best to get back that charm but I failed.. I want my love back what to do any suggestions...

Are you asking how you can make her change back to the girl you used to know? If so, the answer is that you can't.

She is who she is. You either love her for who she is now, or you break it off and find someone else.

Thinsg will be different since she betrayed you,
Like trust fro an example.
She has probably changed as well, so it makes it harded for a connection to be made.
Have you told her how you felt when she left?
Try talking about the whole situation together.
Hope this helps,

Th charm of your love didn't work before, it didn't stop her from cheating. So maybe you should try something else this time besides your charm. Like communicating and being objective and ask her why she bothered to come back, and ask yourself why are you falling for her again.

Honesty and the facts will serve you better than your charm, buddy.
