I was like that for the first 2 and a bit years with my b/f - and we were long distance too! Really nice, really good fun. Enjoy while it lasts, that's what I say. I made the move to be with him, and pretty much all that giddy feeling ended, ha. I think its ok to feel like it, enjoy it. But lay good foundations for the future. see friends and have interests too, so if things calm down, then you've both plenty of good things to do and things to talk about, rather than rely on each other 100%.
