Dear Li Zhe　

　 It’s sad to hear your friend is treating you like this. But don’t worry. Her new boyfriend cannot take your place. In study and life she will still need a good friend like you. Just be patient.

　 You should find some time to talk with her. Try talking to her gently about how you feel recently. Say you will always be her good friend whatever will happen.

　 You should also find some time to spend with her, which will help.

　 Do believe that everything will go well.
