Unlike with poor Ms. Soccer Chick, it seems the long-distance now exists between a functioning couple. The same is always true — if you love each other, trust each other, and protect the best interests and feelings of each other, you can make anything work.
Why, just the other week I had a lady friend of mine — who's husband is working overseas — show me how she talks to him for free over the internet using "video chat." Bless me, I thought that was something only possible at Disneyland in the 1960s.
Just relax. Keep open lines of communication with your boyfriend — checking in once a day is good. Be patient with each other.
And exercise. The increased endorphins will alleviate any sadness.
