When someone physically hits you it's poor judgement to think they won't do it again. If they have done it once and you don't do anything to stop it it's more than likely to happen again. That's just the way humans are programmed. We prey on the weak. If anyone hits me I would hit them back. If a confrontation was supposed to happen I would find some way to turn on my phone and record it in any manner. If you do hit a woman no matter the circumstance without proof of it being her doing you will go to jail.
If some one starts hitting you maybe you should get back into your kitchen and make some sammiches
