Thank you, OP, for opening the door to one of the best and most timely COTH discussions ever. 
So this is a general remark, not directly related to OP ‘s situation, because hopefully it doesn’t go this way.
Ladies, speaking of weird, we have now entered a societal phase where things can get flipped.
It has happened that law enforcement has charged the woman with assaulting the man when she was fighting him away. He may have touched her, but he hadn’t beaten her or done anything clearly forceful at that moment (the handshakes and hugs might be viewed that way).
Because ‘abuse can go both ways’, and all that.
Women usually feel at such a physical disadvantage when they feel threatened by a man. If we are going to strike back to keep a man away before what we perceive as an impending assault, to protect ourselves, maybe we go Defcon 3 on him to be sure of the outcome. As one of the videos said, fighting defensively means leaving them unable to come back on you.
Some of the self-defense suggestions in the thread and videos seem to lean that way - overkill is good defense. But. When I was living in New York city, I was advised more than once that if Something Happens in the subway or anywhere else, leave the guy incapacitated, and then run like hell. If no one can identify you then fergodssake do not stick around to talk to the police.
Some of the self-defense suggestion seem to lean the way of — let’s call it ‘decisive’.
On principle, I am all for it. Let him have it.
But be wise about how are you do it, and what you do afterward.
Example of this from the news. Some of you may have followed the saga of Gabrielle Petito, who was murdered by her partner and companion, while they were together on an extended road trip. A few weeks prior to the murder, the couple were stopped by police in a small town after someone reported to police what appeared to be a physical altercation between them.
Somehow what the police heard about, or maybe saw, was her punching him in the arm, without having seen that before that he had been grabbing her head.
So the police were going to charge her! They actually told her boyfriend that they were going to do the couple a favor and not charge her and take her in, but just separate them for 24 hours and then send them on their way if he felt safe with her. He was visibly pleased with this outcome.
And by the way, he was an average size guy, while she was a very petite woman.
There is a podcast that did a great analysis of all the mistakes the police made in that situation. Especially their very poor analysis of the dynamics between the couple.
But nonetheless, it’s an example of how a police overreach into supposed fairness can make it problematic to defend yourself physically.
Definitely protect yourself. It’s better to be charged than to endure a beating or a rape.
But keep in mind that there are legal parameters that may follow the incident. Hopefully it does not work out like that and the police use common sense. But like everything else, it helps to be aware.
