In love over then net

hii..i met this girl over the internet n we both got along we exchanged numbers pretty soon n were chatting over the phone for upto 10 hours a day. we saw each other on the webcam at nite times and exchanged lots of pictures.. after 2 weeks or so she was begging me to come and meet her in london but i was way up north and had my exams at the time...anyway we decided to meet sumtime in summer after her exams....

but then all of a sudden she was too bussy for me... never answering my calls or txts even tho she use to say she loved me so muchhh...n i liked her alot tooo..

now i cant sleep cuz i still think about her but its as if shes stopped linking me all of a sudden..
wot do i dooo
