Hi there! I have had this happen to me before but with me it was after I had a major surgery. After my surgery we talked somewhat; she came and seen me once when I recovering for months. And all of a sudden she stopped all contact. I didn't know why and nobody else did either. The friends that I didn't expect to stay by my side did and I'm grateful for that. I am in the same situation you are in now, again. It does get better and keep on talking an meeting people!
