I haven't told him

Well, most long distance relationships don't work unless there is serious devotion. Nature will take its course in one way or the other, don't worry.

Well, go with it! Just let it all happen and get as much happiness as you can out of it. If it goes sour, that is life. it might hurt but its better to have enjoyed the time you did have together.

Best of luck!

That's part of the problem, we have discussed all this. Have planned the future, have planned and talked about everything (its been 9 months). Yet still, I doubt it but don't want to talk about it for fear of losing him. Which is somewhat irrational.

Now is the time to talk about it. If you have doubts now, they'll be regrets later. See how he wants to approach it and see what situations you might feel you are in. Are you going to keep in contact every two days? Are you going to share details of each others day? What about sexual frustration. Will you both take time to set up the web-cam? Discuss what kind of dedication to your relationship you want to delve to, or just end it now and be happy with the thoughts of what you had, not of what you -think- it could have been.

Best of luck!
