I being a girl wud say, she is not emotionally with you. for girls emotions are equally important in anythng. so first care for her, ask her if she is fine... do it wen she wants it....
i agree with the last post/reply, you should talk to her and find out what's going on and if it leads to getting medical help then that's okay.
Good luck by the way! :)
You can. First I suggest talking with her to find out what is going on with her and maybe why she doesn't feel anything.
