if it were me, i would seriously contemplate how i got in this situation to begin with,so i could avoid further such situations,and learn from my mistakes. also anyone that raises their hand to a woman is not a man,and any woman that would use violence on a man clearly doesn't know a MAN from a BOY
You have a right to defend yourself in that situation but me, I'd hit her where it's really going to hurt and take legal action. That's assault. A punch back hurts for a little while where jail time and fine and a record hurts a hell of a lot longer.
Regardless if how you retaliate, you'll most likely find your self in court. What on earth did you do to her? Did you try to still her man? If it were me, ahhh, I know I shouldn't say this, but, I gotta tell the truth, I'd hunt her down with my ball bat, then I'd hunt down the two guys, there is more than one way to skin a cat!!!!
