To quote your own words “Goes to show you how blinded one can be when abuse becomes so normal .. you no longer recognize it as a problem until it's too late..”

Sadly your children experience abuse as their normal because that’s all they know (just like like that’s all you knew snd that’s why you choose this man) and they are too young to make sense out of it.

Chances are high that your children will choose abusive partners for themselves because they’ll gravitate towards that as it’s their familiar and their normal, the only life they know. Unless of course you find strength to get them out of this. They are still young snd it’s not too late

Good luck in finding your strength and doing the right thing
