What do you get out of this relationship now exactly, what still keeps you with your abusive partner?.
I think you will regret staying rather than leaving; no abused woman has ever regretted leaving, regret comes about by not having left sooner. The only acceptable level of abuse in a relationship is none.
Such men like you describe as well do not change. Women in poor relationships often write the good dad comment when they themselves can think of nothing positive to write about their man, just as you have done. He is a not a good dad to his kids because he abuses you as their mother, they are being emotionally harmed by him abusing you in such ways. They pick up on all the vibes too both spoken and unspoken.
You talk about being super responsible in parenting, that is itself damaging. That makes for you being hyper vigilent and I am wondering if you are codepedent as well. What did you yourself learn about relationships when growing up, what sort of an example did your parents show you?. Where did this whole idea of you cheering up and trying a bit harder nonsense come from?.
Do not do your bit here to continue showing your children that this relationship is still acceptable to you on some level, they are learning about relationships from the two of you after all. Their home should be a sanctuary, it is akin to a warzone really because your bloke has taken it upon himself to conduct his own private based war with you.
You would not want a loveless relationship for your kids as adults would you so why is it at all acceptable for you? It is not. Men like this target women and hone in on all their insecurities and vulnerabilities to exploit, you were targeted by him really. And abusive men generally hate women, all of them.
Abusive people are not nasty all the time but the nice/nasty cycle is a continuous one and that is what you are still in with this man. He will continue undoubtedly to be bloody minded and difficult once you have separated as well but that is no reason to stay either. There is no good reason at all for you to stay with this man.
You have a choice re this man, they do not. Please call Womens Aid also on 0808 2000 247.
