Sorry. I know that there are a few threads on this subject, and if you feel that I'm adding to them unecessarily then please just don't post, but I just wanted to offer a thought or two.
I'm a bloke. I have been in a relationship when I was hit by my partner (not DW). It was abuse and so, I suppose, that made her an abuser. But she was a lot more than that as well. She was someone who had suffered a very close family bereavement and couldn't deal with it. She was a loving, intelligent person. None of this justified her hitting me, but it did provide context.
I do find some of the knee-jerk reactions to these things slightly worrying. There seems to be a train of thought that abuse = abuser = end the relationship now. This works very well online, where we don't have to face up to the inevitable complications, subtexts and grey areas that real life presents us with. The flip-side is that people posting these messages are often in a vulnerable state and can be more receptive to such black and white judgements. To label someone as an 'abuser' without the acknowledgement that there will be other facets to their character, personality and history is reductive and sometimes can create a monster that is no reflection of the person in the real world.
Don't get me wrong. I have read accounts of horible abuse on here and I am absolutely of the mind that some things can not be worked through and some situations must be escaped from at the earliest possible opportunity.
I agree with the sentiments that someone expressed in a thread a little while ago (think it was called "Listen up" or something).
I suppose that I just think that in the majority of cases, the best advice that can be given online is to suggest someone gets hold of proper, professional advice or at the very least some support in the real world.
Not suggesting that there aren't people here who offer excellent advice and support adn I have no doubt that many people are also grateful for the help and support they have received from MNers. But just wanted to put my perspective.
