well let me tell you this first of all negative mind can ruin a relationship. always think positive until you see by your self
even if you hear 4rom hundreds of people i suggest you comfirm 4rom her first.i believe f she loves yu the way you do i dont think she will have the mind to do that.
also communication matters alot ask her questions about other guys definitely i believe she must have people disturbing her ask her how she feel when you are not around and 4rom her answr you will find the truth,,
