[TX] Hopeful dismissal of false 3rd Felony Assault

Hi everybody. Here’s my situation.

Partner and I went to the bar, bar is by side of a highway We got in a drunken verbal fight I ask for my keys and step away from the vehicle to cool down and sober up before we leave I walk to the side of the enclosed patio of the bar, which is near the highway Partner gets worried I’m going to go for a walk on the side of the highway, tries to get my attention by grabbing arm from behind I didn’t know who or what was happening and I panicked and punched backwards hitting him at questioning by police he says I strangled him (he even admits after the fact that this is not true and I did not intentionally assault him) I am charged with a 3rd degree felony assault impede breath

We want to get this fully dropped. He is the only witness and the victim in this case. He is willing to state that I did not strangle him and I did not intentionally assault him, I was just startled by my arm being grabbed while walking the opposite direction.

How likely is it he gets an assault charge or a lying to police charge instead based on this statement? I already paid the deposit for my attorney, they seemed confident that that wouldn’t happen because stuff like this happens all the time. I’m just a truly anxious wreck and hope I can get some advice or a virtual pat on the back. Please be gentle. This is a first time offense.
