It just means that she is not the right one for you and you will find a better girl. Trust me, you will. It happened to me before. When your right girl comes, you cannot miss it.
I know my wife from ICQ. I did not reply much from ICQ because too many annoying girls tried to chat with me. However in that particular day, I just felt the urge to answer her request. We ended up chatting and chatting. And now she is my wife. It was easy for me to miss her request and I would miss a good wife. Cannot escape fate.
