I think that the no-contact strategy is the best. I separated from my now husband for 9 months, but my message is not to tell you to keep hoping that one day you will be together again, but that you can indeed break up without contact. I would have a calendar where I would mark with an X the days with no contact, and the level of pain with teardrops. Sometimes it was a bunch of teardrops, sometimes only one. Then several days would go by without any tears at all. This helped me know I was healing.
I gave away his clothes to charity, and put away all mementos. I set up an improvement plan of diet, excercise and self-finding.
I think I would have been OK, and moved on.
Good luck and be firm.
You know it's love when the pain of being apart is greater than the pain of being together.
