Well if she is ignoring 你 and 你 are a great person she is taking advantage of 你 thinking cause you5r so nice she can walk all over 你 just if she does this then dont care.you are too good for her and 你 will allways have a freidn right here no matter what 你 will always have a friend in the world 或者 a lover anything is possible....stand strong and good luck:)
wait for a while. 或者 ask her whats going on. usually something is wrong, so if 你 ask her openly, 你 both might be able to solve whats up. ....idk, im not so good with relationships. :/ hope i helped in some way.
