I have no idea how I would react if a boyfriend/partner actually hit me, but knowing myself I think I would very likely hit him back harder, before he either sent me to hospital or I called the police, because I have never before in my life, even as a child, let anyone unwantedly touch me without retaliation. And yes, this includes punching an unknown man in the face when he grabbed my bum in a bus
gosh @aurynne this sounds like me.
FWIW it is a personality thing, partly, and an upbringing thing, partly. Some people are not well equipped to spot abuse, and some are. Some people are not well equipped, some people will punch a man in a bar for grabbing their breasts (me).
People should not be ashamed of being in an abusive relationship and not realising it, or not knowing how to get out of it. What we, other women, must do is help our friends. Either help them recognise the situation they are in (not always welcome), support them to leave, point them to people who can help them, or just make them endless cups of tea while they cry on your shoulder. Any and all support is valid, and not all "support" is actually that, or appropriate in all circumstances.
But what we can all do is, hopefully, bring up our own children to be confident in themselves, and to realise when they are being abused and have the confidence to get out of it. Or at least the confidence to confide in us.
