Not taking his lack of contact personally is the way to go, well done, definitely helps the PMA.
I wonder does he see the new improved you or is he still thinking of you in terms of how you were a year ago. Does he notice and remark on the changes. I know DB is about showing the other half your changes rather than telling them, but I do sometimes wonder if it’s noticed. Have any mutual friends noticed and maybe pointed it out to your H? This happened to me and my H was peeved to say the least.
