Thanks for the update.
As for having an attorney, you can ask the judge to make your husband pay an attorney for you, especially if he was the primary income earner in your marriage. Many attorneys will at least talk to you and see if this is a viable option in your case. So, look around. Your chances of success, however that's defined, will be higher with an attorney at your side. You could also contact TN Legal Aid. They offer free or low cost legal services for folks who qualify financially.
I understand that you don't want to cause your husband to have a criminal record or get in trouble, but unless he's willing to ask for help himself, there's not much you can do other than protect yourself and your kids. You can't force him to accept help. If he doesn't think he has a problem, he's not going to voluntarily agree to treatment, counseling etc., no matter how much good that would do for you and him and the family generally. Until HE wants that, you don't really have much control over his decisions in this regard.
As for supervised visitation, that's a good idea. I would not be there, however. If I were you, I'd ask for the visitation to occur somewhere that is supervised but where you are not present. It's just asking for trouble.
Regarding the protection order, you can get a civil protection order, but it results in the same thing - if he violates the order, he could be held in contempt of court and/or arrested. I'd stick with the order for the time being.
Finally, the children. I mention CPS (as others have also, apparently) because I've seen the scenario I warned you about happen many times. Here's an example: mother and father live with children. Father gets angry and hits mother. Children see it. Mother is a victim at this point, since this is the first time father has hit her. Children are also victims in a way, since they shouldn't be subjected to such things.
Imagine if this abuse happens day after day, every day. Now, mother is not a victim, she's a willing participant. ANY court is going to look at this latter scenario and decide that the mother has failed to protect her children and that the children should be removed. That's because mother is allowing herself to remain in a situation where she's abused, the children see it, the children shouldn't be involved in this sort of scenario, and the children don't have any choice to get out - but the mother does. It's the mother's responsibility (in this scenario) to get the children away from the abusive, unhealthy living situation.
Adults can choose to be in an abusive relationship if they want. If mother and father (above) had no children, it's perfectly fine for her to remain and be abused, if that's her voluntary choice. (I doubt it would be truly coluntary.) But children don't have a choice, so it's up to the parent to think of the children first, not what the parent wants.
In your particular scenario, you've had two protective orders taken out in nearly as many months. Both a court and CPS are going to question whether you're willing to protect the children (and consequently yourself) from the abuses you've suffered. If they perceive you're choosing the husband over the kids, they may remove your kids.
I'm sorry to be so blunt, but this is a harsh reality. It doesn't mean you and the husband can't EVER reconcile and get back together. You may be able to in the future. But if he's not willing to seek help right now, and doesn't think he has a problem, you need to set him aside and focus on the welfare of the children and yourself over the marriage.
