Is long distance love worth it?

It can be if both people have an end date in mind, talk often, visit when possible and trust each other. It tends to struggle when there is no plan to close the distance or when one person carries all the effort. Agree on how long, who moves and how you will stay close in the meantime.

Keep your distance, do not act on it and give yourself time. Tell a trusted friend who is not involved. If the feelings are strong, reduce time together. Never try to break up a relationship. If they become single later, you can reflect again.
