If you want to express your love to a girl with a gift, you must be romantic. Because this girl is going abroad, I think it is better to give her some necklaces in addition to roses, which can be preserved forever.
First, I recommend you a customizable sterling silver necklace. This necklace is simple and fashionable, and can be customized with personalized name letters. You can customize it with the girl's name letters. Girls are very smart. They will understand your intentions after receiving your gift. She should not have the heart to refuse such a thoughtful gift.
Second, there is a saying that giving a watch to the opposite sex is a gift to express love, representing the thoughts of every minute and every second. You can buy a couple watch. If the girl likes you, you can wear it with her.
Third, a bouquet of roses and a box of chocolates are always the easiest to move a girl's heart. Choose a large bouquet of 99 roses for roses, and a heart-shaped package for chocolates. It is best to engrave words, such as "I love you". As long as the girl has a little affection for you, she will be moved.
