Hi!
I'm in the same boat.
I'm American, married to a British citizen
My timeline so far is as follows:
Completed biometrics: Feburary 21
Received an email stating "Your application is currently being prepared for consideration by an entry clearance officer": Feburary 25
Sent my docs: February 25
Package was marked delivered by DHS: March 2, 2017.
I'm sure I speak for all of us when I say, I surely thought I would have heard something back by now.
