Yeah...I'm looking one of these straight in the face right now, and I don't know...you really have to figure out a lot about boundaries, rules, etc. Will you be monogamous while apart? Do you want to know if they're dating or not? Can you deal with going on your SO's MySpace or something, and seeing a silly woman write some sweet nothing in their comments? It could happen. Doesn't mean they don't like you, or aren't thinking about you, or whatever.
LDRs are great if you have enough things to do to keep yourself from fretting over what could be happening somewhere else. There is always the possibility that the freedom of distance will allow for the other party to fall in love and drop you without really thinking much of the effect that will have on you.
I'm sorry for sounding so dour about this, but I've tried to do this twice before, and I've never ended up on the winning end. I don't know if I'm going to subject myself to even talking to the guy in the present situation after he flies back to Europe precisely because I don't want the possible heartbreak.
