Send a text message to your girlfriend, and her girlfriend will reply with a long speech.

Girls think a lot. You never know what they are thinking. Maybe it's better to call, but don't call every day. Besides, she has her own business. Friends at home may be busy, so you will be anxious because you are not around. First, let her feel that you care about her. Text messages can't explain the problem. Better call. Then, because of the distance, she may feel alienated. If you know her home address, you can occasionally give her a surprise, such as contacting the flower shop in front of her house, sending her a flower, or buying something she likes online, so that she can feel love and look forward to meeting after the holiday.
