<human>: Summarize the given text in a few sentences.

Long story short, we were struggling with a lot of issues in our relationship. I cheated (which I know was wrong and what has led to this break-up) we tried to work through it but he felt he couldn't so ended it. I love him very much. 

How do I move on from here? How do I help myself heal? We have put in place no contact as he has blocked my number and has blocked me on Facebook. 

I haven't been single for a very long time and the thought at the moment of never seeing him again tears me apart. I just want to be able to heal properly without causing myself to much damage.
