Physical abuse is a no-no. Verbal and emotional abuse is also a poor way to treat those that we love, but it's not necessarily the only a one way street. Some men often physically abuse their partners because they cannot communicate at the same level or speed as their partners. This is not an excuse, it's a description of the process that sometimes occurs.
Women castigate men for physical abuse, and rightly so, but I believe that a lot of women have become much more verbally agile than men - and their ability to dominate arguments and conversation with greater speed & more oblique comments puts them at an advantage - this can be true for men too, but not in my experience. Sometimes men who cannot keep up with the flow start speaking louder, then begin shouting as voices are raised because their opinions are not heard. It's counter-productive for anyone - a woman or a man - to seek to win an argument by talking faster, or louder than the other or by making several points at once that cannot be simply or serially rebuffed.
Men are encouraged to keep their hands to themselves, and this is right. But then if men should keep physical contact to the same level as that of the weakest or least capable particpant in the argument, surely the same applies to verbal abuse - and men are often weaker here too. Therefore women - or men - who occupy these conflicts should ensure vocal levels and point making are in keeping with the ability of the least capable. Being dominated by a barrage of arguments that don't hang together, or cannot be rebuffed or disputed as they are made is no better than being dominated by someone who can physically force you to stop talking or emotionally cripple you.
My advice is - if you do this physically, verbally or emotionally, you need to stop. Man or woman, the weakest sets the level.
So, guys - make sure you're not loading yourself with guilt for something you've been made to feel is your fault - if it is, you need to stop.
Set rules for conflict resolution.
You cannot make someone come back or try again, you need to provide an environment for them to WANT to do so. Good luck...
