things that my SO and i did before we were able to see eachother more frequently included skype and online scrabble games. we skyped a LOT. that alone is a great way to feel like you're closer than you really are, and let's you learn more about how they are as a person (mannerisms etc.). We also found an app for iphones named Couple, which basically creates a facebook thing for you and your SO. you can post pictures, draw together, send messages and even thumbkiss! check it out here. i've even heard of people who go to the movies together (but apart) where you each go to a movie or watch a certain show and discuss it later. my SO and i still do that type of thing, but with books... it keeps you connected , which is important. :)
