Your husband is both physically and emotionally abusive, and he will NEVER change because it's too easy to stray over that line again once it's been crossed. In fact, this is a classic abuse pattern: he hurts you or threatens you, then acts all nice for a few weeks or months as if he was sorry for what he did.....until the next time he gets angry with you.

He is also gaslighting you (making you feel crazy by telling you things like you don't remember events correctly) and is verbally abusive as well. How much of this are you going to endure before he drives you off the deep end or kills you? This is only going to continue to escalate as he becomes bolder (because he's gotten away with the abuse all this time---what's going to make him stop?).

Please, take your kids and go to the nearest women's shelter ASAP. It's only going to get worse if you don't fight for yourself!!
