Im sorry to hear that man. Basically i had an online relationship like that except that was 2 years ago. I'll tell you what happened a bit because this will help you on your answer. Basically the girl kept saying she was busy and busy every day doing HomeWork. Untill 4 days later she told me that she didin't have feelings for me and she HAD BEEN DATING SOMEONE ELSE for those FOUR DAYS.

Anyways man im just going to tell you this... ITS OVER im sorry to say that but that's life. I mean if she doesen't talk to you atleast once or something in two days then she obviously doesen't care for you. What you need to do is forget about her. Because basically if you keep giving her space shes going to find another guy or try to devolop a relationship. Anyways that's how it goes buddy i hope this helps.
