Lolly, you're right in that you may read these answers and see people assuming your dh is a "stereotypical abuser" who is awful and doesn't love your etc.
But I need to tell you, as a woman who's left an abusive dh: abusive people are actually nice most of time.
It's my belief that they do often love their partner.
But the problem is that they don't know how to love like a normal, non abusive person. They learned very very early on that the way you love someone is to hurt them so that they are weakened and cannot leave. They learn love, but within their definition of love, is an aspect of brutal control.
They can't help themselves and may even realize that they are doing wrong - BUT - they can't change. that's just how they are.
And the painful truth is that their partners need to choose who is more important: is it more important for the abuser to keep having someone who will take the abuse? Or is it more important for the victim to get away and live free of abuse?
The thing that clinched it for me, when I left my marriage: I realized that, as long as I was there to take the abuse, I was actually making it impossible for my dh to make a change in himself.
I was making it possible for him to keep believing/lying to himself that the abuse was ok. As long as I was in his life, I was responsible for the abuse in that I was saying to him, "it's ok, you can keep doing these things, you don't have to change".
HIS only chance was ME leaving and not looking back.
As long as I stayed in the marriage, I was effectively making it impossible for him to change.
Sad but true.
It was wrenching to leave him, I fought with myself about it, I really did. But in the end, I realized I had to be the brave one and take action for the good of me, my dh, and the dc who were learning dreadful things by being in the home and learning the dynamic (and that dynamic INCLUDES the times that he was nice to me - because the "being nice" parts were, I see now, just part of how he kept me at bay, confused, telling myself he wasn't all bad).
Think it through Lolly. Please love. I think you need to make a plan to leave. This can't carry on. It's hurting everyone - you, the DC, and yes I include him in that, as unpopular as that may seem in such a thread.
