Part 1. Maintain a normal relationship

1. Stay connected. Since you won't be seeing each other in person, it's important for you to establish an emotional connection and maintain it as often as possible. You don't have to have long, detailed conversations every time. Frequent communication, no matter how brief, will be a sign that you are investing enough time and effort in the relationship, and will help you stay in touch with each other's life.
2. Talk about everyday, insignificant things. Don't feel like every conversation needs to be serious about your relationships, your hopes, or your dreams. Instead, focus on the little things that a couple living together would talk about - grocery shopping, household chores, changing the decor in the apartment.
3. Try to get to know each other better. As with any relationship, you should take the time to get to know your partner well and learn to understand them. In conversations, pay attention to what he loves the most (hobbies, interests, daily activities) and try to find out more about it, then you will have more topics to discuss.
4. Remember that your partner is a person just like you. Distance can not only heighten feelings, but also cause you to idealize your partner. This can strengthen relationships, but over-idealizing (thinking your partner is perfect) will make it difficult to reconnect with them as a real person.
5. Support each other, even from a distance. Be there when your partner feels bad, when he has troubles or other difficulties in life. You should always be ready to help: so the person you love will know that you love him.
6. Build trust. Trust is vital to any relationship, no matter the distance.
7. Be committed to each other. Be open and honest and share personal information voluntarily. You should be morally attached to each other and continue the relationship based on personal values, and not on pressure from outside.
8. Don't do anything irrational just because you're angry or upset about something. Conversation plays a key role; when you have problems, discuss them to build trust and bond between you. If you, having made some mistake, are afraid of retaliatory actions from your partner, you should think about whether you need such a relationship.
