I do not want to wait until she is gone and it is too late. She and her family are leaving the UK once the lockdown is over. We have known each other since childhood, and I couldn't imagine not seeing her. We have lived on the same street for a long time. Our families are friends, but our mothers are not find of each other. She and I took a walk past the riverside, and kissed as a way of saving farewell. She is not on any social media, especially not FB, not since she was stalked by her ex boyfriend. It breaks my heart imagining life without her, but her family refuses to say where they're going to live, so I guess this is the end our of friendship.
Should I tell her that I love her, or do I simply wave goodbye?
