This is going to sound crazy but make a deal with yourself first!
A dear friend of mine gave me the following tip after I got dumped/broke off a relationship.
Here is the deal I made with myself. I wrote down my first and last name 500 times and then said every time "I deserve the best". If I was going to get to 500 times written I was allowed to call him if I still wanted too.
Don't know why, but I never got to 500.
Ps. This might back fire. I remember said dear friend once calling me. She had used her own advice and was already at 600. Thats's when she called me. This would be suggestion number 2. Call your friend!
The number will fade. It will. I promise.
