Proposal Idea #8: You’re my past, you’re my present, be my future. Find a bunch of momentos from the day both you and your girlfriend were born until the present day. These could include baby pictures, birthday cards, awards/medals/trophies, event tickets, letters/e-mails, sentimental photos, travel souvenirs, etc. Place your items at several different “stations” around your area, like at a park or around your house. Later, take your girlfriend for a walk, stopping by each station, talking about the experience, feelings, and memorable times. When you arrive at the last station, it should be your engagement ring proposal box. Take the box, open it and propose.
