Hi,
My friend had a serious relationship with a guy for 2 years... soon she came to know he was cheating on her and they broke up, but they have a common source and get information about him, she recently came to know he's getting married.. she still loves him and is in no way open to move on... there are many nights when she calls me up to say she can't forget him...
I really want to help her move on... but I can't see any way...
Sometimes I wonder maybe I'm there too much for her at times...
Please help me help my friend..!
:(

It's up to your friend to move on. You can talk to her and comfort her and be the friend you need to be for her, but ultimately it's her decision to move on and nobody can really help her with that.

Take her out places, hang out, just do normal things to get her back into the routine, if there was one to begin with.
