Sincerety is must

If a friend is not sincere, then unfortunately that person is not a true friend. It hurts a lot when you find this out and you will probably shed many tears. The best thing, though, is to let that person go. When you are in tough times, you certainly don't want a false friend around you. I am so sorry if you are going through this type of situation now. Your true friends will always be by your side.
