Stop looking at their genders you stupid misogynistic moron.

Classic.

The law that you wanna quote so fucking hard with 0 expertise is all about intent.

Actually, it's not. The primary issue to consider is "justification" not "intent". The use of force is generally unlawful unless justified in defense of self or others. A person is justified in using a level of force a reasonable person would deem necessary to stop another's use of unjustified force. Provocation and instigation also play a role: A use of force is not always unlawful if the other party has acted to deliberately provoke the response. Look up "fighting words" to get you into the right area of study.

Here, she initiates the physical altercation by unjustifiably grabbing the glass. Provoked, he splashes her. She unjustifiably strikes him. He justifiably shoves her. He kicks her, putting her back on the ground.

The kick is questionable. It's either an unjustified attack while she's on the ground, or it's a justified attempt to keep her from getting up and striking him further. Since this would only matter if he's the one on trial, and if he's the one on trial, we owe him the benefit of a doubt, we have to call this one justified.

Either way, he immediately retreats after the kick, ending the threat to her, and making her next actions unjustifiable. She gets back up, grabs a beer bottle, and confronts him again. He justifiably shoves her away.
