I'd say that its up to you the time you need to heal back from said break up. After you decide you want to get out of the funk, it just gets better. I spent 6 years in a relationship and we decided to get married, we did and that just lasted about 3 more years. She meant a lot to me and now we're in good terms. The end of it was bad, she got physical, lots of tears and lots of pain. After I moved out, I took some time for myself. I struggled and even times when I wanted to crawl myself back to her feet, but I never did. I found help volunteering at a family center and decided to go through with it. Found things I had to fix on my own, learned to live by myself, learned to trust again. I went thru a couple of short dates. Nothing to write mom about. Most of my friends were already in serious relationships or married. So there were a lot of lonely nights. My ex would cross my mind but it wasn't the same feeling. One day I decided to buy a motorcycle, I met different people. One day we were going to a meet and a friend had an accident a month before that. He wanted to tag along but he couldn't even drive. I posted a message on this forum we all were part of and the reply was from a girl who lived a few minutes away from my friend. She picked him up on her car since she was looking to buy her first bike. I still remember the smile on her face as they were walking towards us. Then, up close I saw the most beautiful hazel eyes I've seen. We became friends and started hanging out a lot. She got her bike and we would ride around town. She kissed me first and then we became official. Going on strong for over a year. And there are differences, there are misunderstandings, there are mistakes. But as long as there is communication, you can fix most of the problems. There is life after a break up. We just need to defeat the fear of being happy.

TL;DR: After divorce, met my SO when I decide to make changes in my life.
