She doesn't have to press charges - that's the state's call. And in NY, this isn't going away and the court isn't going to care about extenuating circumstances. When you have an incident of "fight", even mutually, that ends with someone with an injury, what happened in the middle, whether intentional or not, isn't going to soften the charges. Look at it this way: if you go into a convenience store, and decide to shoplift a pack of gum, and the clerk sees you and you run to avoid the confrontation, but trip and the gun in your pocket (that you never even pulled out) goes off and kills the clerk, you'll be facing armed robbery and murder charges, even though you never touched the gun or intended to hurt anyone. Here you've got a history of fighting, you taking action to prevent her leaving (from another incident), and her getting injured as a result of reacting to physical action taken by you (she didn't want you to "hug" her and her act of self defense led to the injury).
The larceny charge will probably be the easiest to combat (although since abuse isn't just about hitting, but about CONTROL ISSUES, it's totally feasible that you hid the phone which is probably why the officers included those charges) - but the unlawful imprisonment will probably be the one to sting you. She's an adult - she can go out in the snow wearing a bikini if she wants to and you've got no right to make those decisions for her or deprive her of the means to do so.
She could have gone to the ER and said "I tripped over the dog and hit my head" - but that's apparantly not what happened. Who got the police involved?
And learn to quit fighting when you're intoxicated, otherwise you risk incidents like this one repeating themselves. You might not have hit her or directly caused the injuries, but there are definately some classic warning signs of control issues here.
