long distance relationship

I've been in a long distance relationship with an amazing guy now for a few months,we've known each other for nearly 2 years,we've been through so much and he's my best friend and my boyfriend and we both love each other so much,we've been talking every day since the day we met but the only thing is we live hundreds of miles apart from each other he lives in a completely different country and he's going away soon and I won't be able to talk to him or know if he's okay,we've been planning to see each other for a while now and we really want to but the problem is since I'm only 19 and he's nearly 21 we're so young and can't afford it all yet,we would have to wait years for that to happen but we've already waited for so long so I just wanted to ask for your help so I could surprise him by going to he's country when he gets back and just be with him maybe just for a little while,we all know how it feels not be with with the person you love more than anything,not to feel his touch or smell him...
