I've never laid a finger on her and frankly i find that comment offensive. The idea that I would react in that way is obviously not true from everything i've said on here. I'm sad you've misunderstood (intentionally or not) the well intended advice i've posted on here to help young men deal with their better halves.
I assume you are a young whippersnapper who is in danger if they are not careful of going down that route. Violence isn't the answer. We all get things wrong sometimes and when my girlfriend does, the situation is resolved with the tongue and not with the fist. I've given many examples of that on here. Equally when i'm wrong the situation is corrected using words not swords. (Can't think of an example right now, but to be fair i've only given it a couple of hours thought).
Anyway, if I was you. i'd seek help before you do real harm. My thoughts are with you.
A little discipline doesn't do any harm ?
