First of all, the DB didn't backfire. You got yourself healthy and in shape and in a much better mental attitude.
Second, you stopped posting your progress. The more you progress, the more your situation changes. It would have been important to continue posting so that your strategy could have been adjusted. You see what doors have been opened and keep going.
Let's face it, you said your H has been much nicer than before. That's all positive DB. Just because your H has not said he wants to come back is not because of DB or you. It's him.
Right now he's playing the "oh woe is me" card because he sees you doing so well. What's important is that you not fall into that trap. He's doing that to draw you back in to him. He's still blame shifting and saying that it's YOUR fault he hasn't come back (because you don't need him). To try to continue control over you. It happens here all the time.
Don't do that. You can drop a bone over to him every now and then, but only on YOUR terms. You have the power now.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
