I can sympathise with you. although, my situation isn;t quite the same.
For a good six months or so, I was seeing my master at least 3 or 4 times a week, and whilst we didn;t have that much kinky sex. the whole mind control and humiliation type stuff was there pretty much constantly.
He works in the armed forces and was posted in the Falklands, I haven;t seen him for 11 weeks, and he still has another 10 weeks to go until he comes home. When he does come home, he is being posted out of Norfolk and will be a good 400 miles away from me, although we have made a commitment to see each other every other week, which suits me as I train with the TA everyother weekend!
It will be another year before we can see each other regularly again. When I fully qualify, I am going to move to where he will be posted at that time. But hell, it's a long time to wait.
Long distance can work, provided there is a glimmer of hope in the distance that it won;t be a long distance thing forever!
