What is going on with her?

maybe everytime she talks to you or any1 else, she gets sad. i mean, she probably misses her home and by talking with you she will start to miss it more. Of course she should be over it by now... her life is probably changing and you have to respect that. i know its hard when someone changes, but just bare with her. lol. you ask the questions and just tell her that you dont like how she wont open up to you and talk with you anymore. good luck and take care:)
