Here is a line from the secret book: 
BOB PROCTOR Hold an image of talking to an old friend that you haven’t seen for a long time. Somehow or another somebody’s going to start talking to you about that person. That person’s going to phone you or you’ll get a letter from her.
Try it :D

I know how you feel but trust me if you contact him you're gonna regret it.  Because deep down inside that's not what you want. You really want him to contact you, right? I know it's hard. It's so many times that I wanted to pick up the phone or reach out to my ex on FB. But if you want optimal results (instead of instant gratification) you have to let HIM reach out to you. Veronica mentions in her book that contacting your ex first signals lack to the universe. That's not the vibe you want to emit because I'm sure your ex will pick up on that and all you will do is push him further away. If you don't have her book, pick it up.  You need to become really busy so you're not thinking about your ex all the time. Because when you're in a relationship with somebody you're not thinking about them all the time because you KNOW that you have them. The goal isn't to completely forget about your ex but it's to not OBSESS over them. What do you do during the day? Do you work? If not, get a job. Volunteer on your down time. Plan a weekend getaway. Go out shopping or to eat on the weekends. Signup for a class or get a hobby that requires you to leave the house.
