very considerate boyfriend. My girlfriend is going out to study for further education. She should be supported and encouraged. But one month is a long time for lovers. However, distance creates beauty. Being apart for a period of time will make each other miss each other more. It is also a different way to strengthen the relationship. Only when you are lonely will you really think of the person you need.
Haha, so, it is recommended that you can give her a small gift to keep in touch with her. You can buy a DIY color-changing water cup online, or a letter necklace made of her name. Both are good.
