This is the second time this has happened to me. Last time I my best friend ditched me. What should I do?

Maybe you should talk to her about her feelings find out if she is gay or bi before you say anything if she is ask her how she feels about you and if she likes you then tell her if she does not like you like that best to keep quiet about things. I hope this helps if you want to chat you can email me. Best of Luck to you I hope everything works in your favor
