Don't listen to this guy. I mean NC is good but not in case if you hope for going back with your ex. This guy used NC for a bad reason. NC is to help get over your ex(probably bad and hurting) relationship AND NOT to get back with your ex. This guy is a good example and evidence that I'm right. This 'crawling' girl left him AGAIN , causing more hurt. If he would listen to our advices, he would have avoided his pain atm, but he's hurting again instead.
People, continue with your NC, is very important, actualy one of the most important things in break up. It will help you heal your heart faster and let you be happy again. It's also very important for your future relationship. I don't think any future partner would like you to keep contact with your ex
Stay strong there people, peace will come
