First, communicate well! You have to express your thoughts that you have, express them directly because she can't know what is in your mind. Then try to listen her carefully, let her finish until the end of what she thinks without interrupting the conversation.
Second, try to interact regularly with her, there must be a time when you don't have time to talk with her because your schedule is getting crowded, but you should take the time to talk with her because the relationship will be troubled if she keep herself unpleasant things. But besides that, give her freedom because we can't ask her to give all of her time for you. Let her play with her friends or family. Appreciate her freedom to do something without you, because this is not a bad thing.
Third, live a relationship with respect each other. A new relationship will definitely be fun, but you still have to show respect for her so that she respects you too. Even if you are upset, keep respect her. You can appreciate her from a little things she does like say "thank you" for her kindness.This little things will support a healthy relationship.
And the last, don't forget to spend your quality time togethet. Most couples only spend their time chatting on their phone rather than meeting directly. It can cause some miss communication. By giving the time to meet, your relationship will be fine.
Of course, besides all of that, we need a big commitment to live it, so we can express ourselves and develop each other to reach a better life together. But many couples underestimate things like this. As a result, they have many unsolved problems during relationship.
