Dear Annie: I had a high school boyfriend 47 years ago but left him. He came to my house the day before I was marrying someone else and begged me not to marry him, but I did. Long story short, after getting divorced, I tried to find him, but I couldn’t. I married again and got divorced again. I then focused on trying to find him again only to find out he’s been dead since 2007. I don’t know how to process my guilt and grief and wondering what might have been. He never got married nor had any kids. Missing him after all these years. -- Nostalgic and Regretful
