I would have been perfectly happy to continue when I was younger, so keen to be fair, so keen to give the benefit of the doubt, so sure it would be a mistake, tripping over myself to believe the story of high drama and terrible cruelty by the crazed woman scorned...
But that’s because I was young, and damaged myself, given no healthy relationship models growing up, and absolutely no idea that I deserved protecting or caring for myself.
Now, being older, uglier and a lot less naive, I’d say no. You don’t owe this man anything. You certainly don’t owe him your safety and risk to your future wellbeing, just to ‘be fair’ or give him a chance.
And on the balance of probabilities, it’s far more likely that the man had beaten up this woman, rather than a woman concocting lies to trick the police into arresting and keeping him for the weekend... although society points us in the more ‘reassuring’ direction of ‘crazy girlfriend spreading lies’.
