You can contact once every few days by sending a text message.

Say hello twice, once in the morning to show your concern for her, and once in the evening to show your love for her. But don't make her impatient by talking nonsense. However, it doesn't matter how many times it is special. For example, if you are sick, you should make her feel that you are good to her. Don't use text messages at this time. You'd better show your sincerity. Dude, it's up to you!
