Does your partner treat you like a child? Most abusers who use verbal abuse as their prime tool will treat you like a misbehaved child, yelling and disciplining you as they demean and point out your every fault. However, if you try to correct them, get ready for a seriously defensive and angry backlash.
Everyone is going to make a mistake now and then - and most healthy people will be able to look past those mistakes and not get all worked up about it. Someone who's an abuser won't do that - they'll look for ways to criticize for the smalles of infractions. You can begin to think that you're a loser - not good enough - unworthy of someone's love - and that's exactly what they want you to think.
If you're partner is forever criticizing you - or treating you like a child - know that it's THEIR problem - not yours. You can move on - you can find someone who will appreciate you for all the good that you are - while forgiving you for this little mistakes that you make along the way!
