If your daughter is feisty and wouldn’t let a man do to her what her dad does to you.. and that makes you feel proud of her.. imagine how proud she would feel of you if (maybe when she’s a bit older) she learns that her dad was a cheating scumbag and you had the strength to kick him to the kerb. What a good example for her, and your son too. I agree with poster that your son will be more influenced by what he sees than what you try and teach him. If you won’t leave for your own sake OP (which you absolutely should) - think of your kids!
And also as a reminder, 'feisty' women aren't immune from being in abusive relationships. Nobody who knows me professionally / casually would
believe I would 'let' a man be abusive towards me. But the concept of 'letting' a man be like that is very victim blamey. My feistiness didn't safeguard me against abusive relationships, only therapy unravelling the learned relationship behaviour I experienced in my childhood did that.
In my case, growing up in a household I would say was tense and walking on eggshells rather than abusive (I was always incredibly close to my mum and still am) did enough damage that I didn't realise real life couples had a laugh with each other, were genuinely affectionate, were cheerleaders and equal teammates etc... all that contributed to my poor choices of partners in my early 20s. Add to that the legacy of having a mum (who as I say I adore and is wonderful) who stayed in a relationship that didn't bring her joy, that saw her try to keep everyone else happy etc gave me the mindset that it's normal to be unhappy with people but still stay together. You said it better than me - kids learn more from what they see than what they are told.
Funnily enough my brother has turned out to be somewhat of a misogynist who talks the talk in public about equality but through his actions clearly believes cleaning, cooking and childcare are ultimately a woman's responsibility and if he contributes he is 'helping' rather than just doing his fair share and adulting.
Because I'm 'feisty' he would think my exes weren't abusive and I must have given as good as I got. We can't win, it often feels like.
But you can help break the cycle by setting an example to your kids when it comes to healthy relationship behaviours. Especially as in the next 5/6 years they'll likely be starting their own entry into the world of relationships. This is such a pivotal age for them both. Please don't make them think this relationship is healthy and normal.
