Umm in the past I have because I had l put my hands on them

I've only been sucker punched once back in college by my old best friend. I never got an apology from him, but I probably deserved it.

If it was an accident and they were sincere, certainly. But anything short of that, I have a hard time picturing how one wouldn't mean to physically harm anyone. It's good if they regret it and are genuinely sorry, but if it was deliberate when it happened, then yes they did mean to. Them saying that would make it hard for me to believe their apology is sincere.

idk i wouldn't trust them anyway they'd do it again

Zero tolerance for physical violence. Not even a slap.

depends

I wouldn't leave them with a way to reach out to me at all, personally

No
