I think the reason why long distance relationships donât work is because of a lack of commitment from both parties and because often the relationship drags on without either person ever planning to move (so no light at the end of the long distance relationship tunnel).

The duration of the relationship depends on a few factors. If the individual on the rebound is available and emotionally stable, the new relationship has a chance of lasting.
