Long distance relationships end in one of two ways.
1. One person moves to be with the other person.
2. The relationship slowly fades away.
One of the reasons most people seek to avoid getting involved in long distance relationships is because they don't want to move away from where they live. They also don't want to risk becoming emotionally involved with someone that is not likely to move to their town.
Another disadvantage to long distance relationships is the difficulty with having disagreements and making up. You're pretty much left to communicate using the phone and computers. (Neither option allows you to see a person's face reacting to what you have to say.) It's easy to ignore the phone and emails when one is angry.
Most people in long distance relationships talk to each other multiple times during the day as well as instant message or send emails. They also take turns going to visit with each other at least once a month or more. They mail each other little trinkets (books, cards, post cards...etc)
However in the end for the relationship to go to" the next level" someone is going to have to move. I would think after 2 years of being together one or both of you would have brought up the subject of moving. If no one was is willing to move then the end of the relationship is pretty much just a matter time.
