Jin, don't under estimate your H. He's not being a wimp. He just doesn't want anything right now. During our separation, my H only called, texted, etc me when HE wanted something from me. Once he got his answer was completely happy to comply with NC.
Meditate on the reason for the way you're doing the no contact. I don't happen to agree with the way that others on this forum have recommended doing it in the past. If you want to try to save your M, there are other ways to handle it that may have better results.
By the way, I always recommend reading Relationship Rescue. I don't know if I've mentioned that to you before. It pairs very well with DB and DR. And, you can implement the methods in the book without your H's cooperation. It also helps you know what you need in a healthy relationship so you can decide if this one is savable.
