There are many things that can assure a good long term relationship:
1. Keep in touch always
Whether you prefer text messages, IMs, emails, telephone calls, or video chatting, keeping in touch is the most important thing you can do in a long-distance relationship. There are even smartphone apps that allow long-distance couples to share photos, videos, send voice messages, and more. A handwritten letter or unexpected gift goes a long way to making your LD partner feel loved and appreciated.
2. Know When You’ll See Each Other Next
Before the end of a visit, be sure you know when one of you will be visiting the other next. If you have a definite end to the distance already on the calendar, even if it’s just going to be a weekend together, the time apart will be easier to deal with
3. Reuniting after time apart can make relationships feel honeymoon-y a lot of the time, especially if you’re visiting on weekends.
4. There are moments of jealousy and insecurity in even the most secure relationships. However, every perceived slight or twinge of envy will be magnified in a long-distance relationship. So, it is very important to trust each other.
