First of all, you can give her a pillow, because you are not by her side, she is alone and lonely. Giving a pillow will make her feel full. And she will also feel that you are by her side. Girls are emotional, and they always like such soft things. Moreover, if you give her such a pillow, she can also feel your soft heart that loves her. It would be even better if you can print your sweet photos of the past. Thinking of your past and your sincerity, I believe she will definitely forgive you.
Another way to apologize is to go to her city, suddenly appear in front of her, and tell her that you love her very much and ask her to forgive you. Of course, you can't go empty-handed. You can bring a bouquet of flowers or a customized small gift, such as a customized gift. Another more creative way is that you customize it on the website and then ask the courier company to deliver it.
