When I started dating my ex I knew we would be together forever so I started a scrapbook. It has cool pictures and mementos in it. It may not mean as much now that we have split but it's still a great idea if you meet the right guy. Start a scrapbook. I always told my husband the memories we would experience only once the first time and I wanted to remember and enjoy them. Like our first flight together, a concert, and a weekend away. I was never in love before that and have not been in love since.
