Kroy Biermann Excludes Kim in Xmas Post ... It's Just Me & the Kiddos!!!

Kroy Biermann is highlighting his holiday by snubbing his estranged wife, Kim Zolciak ... and her exclusion is jarring.

The retired NFL'er threw up a snap of him and his 4 kids with KZ -- Kroy Jr., Kash, Kaia and Kane -- with Papa Bear standing proudly behind them and grinning from ear to ear. His caption was also pretty telling on how he's feeling about his marriage/divorce right now.

He wrote, "Merry Christmas from the Biermann’s!!🎄 (-2 😢) I didn’t get a picture of the family enjoying @arianabiermann ‘s church service and I had this taken after @briellebiermann and Billy had departed in the direction of their car as we were almost outside from our service."

KB added, "I couldn’t be a more proud father of you 2 and the littles! ❤️ Got to do better at remembering to capture more pictures." Interesting ... he noted Brielle and Ariana here -- who are actually Kim's biological daughters -- but not their mother.

BTW, no posts from Kim herself ... she hasn't thrown anything up since mid-December.

This marks just the latest up-and-down moment for them ... for now, it seems like Kim and Kroy are on the outs -- this after sending signals of reconciliation just a month ago. Of course, they also had a huge blowout fight that required the cops to called over.

It's proven to be a difficult year, for sure ... and it seems Kroy wants to turn the page.
