Possible trigger with domestic abuse..

Looking for different opinions: My ex husband and I have been divorced for 7 years. We have a 12 year old and an 11 year old. I and my children suffered ay the hands of his abuse until I left. I never called the cops any of the times, so there isn't anything documented. Upon all of that happening, I was left homeless, and was forced to relinquish custody of my children to him because he had an apartment. (this was 6 years ago) We currently have joint custody, he is the custodial parent (he and I have had a long and drawn out battle with court) My children are brainwashed so much so that I havent had visitations since labor day of 2017. (not for my lack of trying) Its a lot of court and loopholes hes using and no, i do not have a lawyer, nor can I afford on and none I've called are taking pro bono cases. Here is my problem. I flat out refuse to get along with him because to me, the abuse that I and my children suffered at his hands....I should never have too. I told him that i would co parent and hate every minute of it with a smile on my face. he told me unless i told our children that everything he ever did was a lie, that he wouldnt co parent. I was bewildered. Asking me to lie and make him look innocent when he wasnt. Am i wrong for refusal to forgive? Even for the kids? Forgiving him knowing what he did to us and what he still does to our children??? Its like asking a victim of rape to forgive her rapist.... its the same but different. Im in therapy...but recently things have happened with court where they're making me pay child support and hes going for sole custody without any reason. Im a stay at home mom to of my youngest child with my current husband, I dont drink, smoke or do drugs and they're treating me like a ceiminal. All ive ever done is fight for them and try to get them away. siiiigh. its ridiculous.
