Your Not alone in this... I relate to how your feeling.. all i can say is stick in there... it does get better...

I met my ONLY and now Best friend (we like brother's when together) on a forum several (8)years ago... We live 100km apart, only get together every 6 months or so.. we send mails when needed... i've found it to be a relaxing helpfull friendship... there's no 'Oh why you not calling/messaging me' or any of that s#! if we dont talk for 6 months, it's fine, we go to the pub and sit for 5 or 6 hours and catchup, as if it's been just days....

Acctualy i'm buying a house around the corner from him and his wife (which gets on very well with mine), so that i can have more of his friendship therapy...

Hope to be moving very soon...
