Most Helpful Guy
Yes, they can. It's not common, but it's not impossible. If you and your SO really love each other, the distance won't matter. Those who say that it does are just weak-willed. BUT, you have to REALLY put in the effort to make it work. The 3 most important factors into making an LDR work are:
1) Communication - That means NO playing games, you have to be even more open and honest with each other, and make an effort to talk at least once a day. Even if it's only for a few minutes, or it's just through text, still make the effort to talk to each other. If one or both of you are too busy to talk every day, then at least do it every other day.
2) Effort - Depending on where you live, at least one of you has to be able to both plan and afford plane tickets to see each other often. Or at least during holidays/breaks (if you're young and/or in high school or college).
3) An Endgame - At least one of you has to be willing to move out of whatever state/province/country you are currently living in, and either move to the other's location or you BOTH move to a middle ground (Ex: You, who lives in California, and your boyfriend, who lives in Texas, agree to move to Nevada or whatever).0THIS IS NOT RELEVANT ANYMORE
