Have faith
Trust is the most important thing in a long-distance relationship. Your love relationship will only progress when you trust each other. Unnecessarily inquiries such as where he is, with whom, why is he, why did he pick up the phone, why did not call back, do not do at all. In such a situation, your partner will understand that you do not trust him. If you do something similar, do not do it at all, because it is not good for your relationship at all.
Do not argue and fight
Suppose you did not like anything about your partner, then avoid being aggressive. Even if you feel bad, it does not mean that you get angry or sit in a fight. Especially in the Long Distance Relationship, if your behavior is like this then it will not take long to break the relationship. Maintaining trust and communication with each other is the key to the success of the Long Distance Relationship.

Promote Common Interest
Even if you are far from each other, but if you have a common interest, then promote it. Like join a gym together or dance or music classes. Share your common interest with each other, what you did in class, how you did it, what new things learned, all these things will maintain newness in your relationships.
Plan for the future
Discussing the nature of the relationship is very beneficial for Long Distance Relationship. If both of you are dating each other, then discuss about taking your relationship to the next level. If you have a Boyfriend-Girlfriend, then do wedding planning and if the husband is a wife, then talk about family planning. Such things will keep you curious about the relationship between you.
