Well, let me ask you, is this relationship going somewhere? As in, do you have plans to see each other soon or move to live near each other?
Because I don't personally see the point of a long-distance relationship otherwise.
My partner and I began long distance. We were across the country from each other. We began talking online in 2005 but it never really went anywhere. We would occasionally chat or something in the following years. But then, for whatever reason, in 2009 I started having feelings for him. I'd find myself staring at his Facebook page all day. I just felt this incredible love for him out of nowhere, which was pretty weird. He ended up telling me that he felt the same way and we began talking online for hours a day. Then he called me, and when I heard his voice I knew for sure. There's just something about someone's voice. He sounded so cute, I just had to have him!
The online talking lasted maybe 2 months and then I finally left my life behind, got in my car and drove across America to his house. I was so nervous as I was approaching his street that I almost had to pull over and throw up, lol. I was literally trembling. It's crazy, but I just knew that I was about to meet the person who would change everything.
We've been living together going on 3 years now!
Anyways, the point of my story is that they can indeed work out and the spark can be kept alive, but I think you need to know that it's going somewhere. As far as keeping the fizzle, you have to talk in detail about all of the yummy/sexy things you want to do together. You have to make plans and get excited for them. If there aren't plans to be made, you really should think about what you're doing, and why. Because relationships take a lot of effort as it is, and long-distance makes them even harder.
