Long distance relationship is said to take place when the couple is separated by a considerable distance.
       I know some people who have this kind of relationship and they said that once you're into it, you'll be used to it. And of course it can't be avoided that you will be worried because you are not on his/her side. When my husband had to go to an army school for a month, I was sad...It was only for a month but it sucked! How much more for those couple who are like a year or more far from each other? I know it is hard...
      I guess for this relationship to work, both should do something.
TRUST is the main thing and of course for a healthy loving long distance relationship , there should be a regular communication.
