I don't necessarily disbelieve the op. I have been through the same sort of journey.
I kicked my husband out with a heavy heart after he hit me in front of the children and I called the police. Prior to that, I had been very worried about his effect on the children, but kept thinking he could improve, and hoping we could stay together.
I was strongly encouraged to get a non molestation order, but tried to cancel this after a week so that we could communicate about him seeing the children. I soon realised my mistake - the whole thing escalated, and I went back to court to say that the best thing for my children was supervised contact only, and that the non molestation order would give us the space we needed to heal and move on.
Social services have now closed my case, but this is dependent on my assurance that I will not continue in a relationship with my husband, and will leave the non molestation order in place. They have made it clear that if we got back together, they would probably be moving to take the children away.
I was offered a straight choice between my children and my husband. It's a no brainer really, isn't it? However, I do believe that marriage is for life. It was only after doing the freedom programme online that I had my sudden lightbulb moment that we can never be a family again.
My children are much happier and much more settled.
maybe the op has just had her lightbulb moment?
