try to meet as much as possible, by flying back whenever you have holidays, also talking on msn can help. but the most important is to meet whenever possible by flying back when u have time. Hope u can survive!
it is all up to you how to handle your longing for your gf. internet is a tool that you can use where you can talk to her everyday and even see her online. get busy with work really busy and time will fly so fast.
Talk on the phone often. Make sure you guys get webcams. That will help. It will be tough, but it can work.
