Be as normal as possible
Stay in touch with each other:
Since you cannot see each other face to face, it is important that you remain as emotionally connected to each other as possible. For this, it is not necessary that you always have long talks, light talks and knowing each other is enough.
This kind of light-hearted conversation shows that you care about each other and are following this relationship with honesty.
This way you will be able to keep complete information
about each other.
If you keep a long gap in your interactions, then your daily activities and experiences will blur with your past, memories and you will start a conversation with those blurred memories in the present.
Use Technology
Learn about the tools of contact used by your partner and adopt the means which are the easiest for your partner to use. You can message, mail, or make video chatting to each other to contact each other.

Contact according to your mutual time availability. If you know that tomorrow you are going to be busy in some work throughout the day and you will not get time to talk to each other, then tell this to your partner well in advance and to meet this deficiency with your schedule Make a plan to talk forward or backward.
Talk about petty Issues.
If you're in a relationship with each other, it doesn't mean that the two of you always talk about your relationship, its future, your dreams, hopes, and serious topics like expectations. Do it Instead, sometimes talk about many other things and events around you or your life like what you bought today from the grocery shop or what happened in the neighborhood around your house, etc. Such things will give you the feel of making your home together later, which you have to do later.
Keep your conversation lightly based on worldly topics, do not go to the seriousness of these topics, otherwise, these things can bore your partner.
