Ok so i have this friend since the this year Feb. We became very good friends soon and everyday she would text me with random and sometimes sweet messages. she is also a really helpful and great friend. Until recently she started to grow distant from me and whenever i tried to talk to her she would give me curt replies. i texted her to ask her if i have annoyed her or sth and she said no. this happens several times and finally she began to tell others that I'm too oversensitive and so on. but she acted that way to make me feel this! what should  i do? i really do not want to lose her.
