I think I mentioned to you that I had similar interactions with my h after ow seemed long gone...each time it was after I had pushed for more or expressed the notion that he wasn't doing enough.
So, yes, you can certainly jump back on the DB wagon...go back to what worked when you first started, keep focusing on positives, maybe even focus on speaking his ll loud and clear. all of that is good stuff and a great way to break out of the rut.
The other option (still db centric) is to just lay low for a bit...iow, "do nothing" -- take a break for yourself, rejuvenate, do good stuff for yourself...the KEY to that time, though, is to "do no harm" -- don't freak out on h or pull back particularly or try to hurt him...just lay low for a bit while you get your energy back.
It takes time, time, time and then more time. But you already know that.!
