Things got better and by the 7th month of our marriage he was an anxiety ridden mess and left me because he needed space.
Can you expand on this a bit? What exactly was causing his anxiety? There must have been one or more triggers. Did he seek medical help? Major anxiety disorders need to be treated.

Quite right, he's in the "puppy love" dopamine release phase. It lasts anywhere from a few weeks to 6 months after which reality comes crashing down and they'll start to realize that A)their new situation is no better and probably worse than the one they left and B)they left a trail of wreckage in their wake and need to atone for it. There's no guarantee that will happen, but often it does. I think you're doing the right thing as far as no contact, you just need to leave him to it and see if he has an awakening. You should also read DR and start working on yourself, it's a very helpful book.
