Revenge against the married woman who slept with my husband?

Okay my situation is a bit different from any of the others that I've read on here so I thought I'd start a new discussion and see if anyone has any advice because I could truly use some. First of all let me say that I am NOT taking ANY of the responsibility for this away from my husband. I immediately filed for divorce & we are going thru the court system right now. However I have alot of anger towards the married woman who slept with my husband. Again, I know that he was just as wrong as she was and I am NOT trying to excuse his behavior however after getting to know my husband in a semi-professional setting he opened up and told her that he was in treatment for sex addiction and told her about the steps he was taking and the process that he was going through to break free from this addiction. Within a very short period of time she had him over to her home to do some professional contracting work for her & her husband. While he was looking over the work to be done, she went and changed into a robe with nothing underneath & began rubbing his shoulders, etc. Again, I AM NOT excusing my husbands behavior because he could have easily told her no & could have easily removed himself from the situation and he did neither of these things and instead had sex with her. They continued this for awhile until she started demanding that he leave me & our children & threatened to expose him by telling me what he had been doing. She even told him that she had driven by our house to see if I was home one day. This prompted him to tell me everything. I immediately threw him out & filed for divorce. And then I called her to let her know that he had told me everything and that she needed to leave him alone. She proceeded to try to tell me about all of the things they had done sexually and I just hung up the phone on her. She continued to call me that day. As I have stated, I am in NO WAY trying to absolve my husband of his actions, but I feel as if she used the situation and the knowledge that he had shared with her & her husband to seduce him. Of course he could have said no & he didn't and that was his fault & he is the one that is paying for it. But she actually had the nerve to tell me that I just didn't understand because her husband is so much older than her and she just had needs just like my husband and they were able to help each other. She didn't help him, she has (they both have) destroyed his life, literally. He has lost his home, his children, and is very close to losing the business we have spent more than a decade building. He is remorseful to the point of contemplating suicide and he is now seeing another therapist for that. I have some sympathy for my husband because I see how very bad he feels for what he has done to our marriage and our family and because I know how badly he has struggled with his addiction. Both of our extended families have been devastated by this also. However, I feel nothing but anger and vengefulness towards this "other woman'". She was in no way remorseful. She not only knew my husband was married she threatened to expose him if he tried to stop seeing her. At first I didn't believe anything that my husband said in regards to her & it was only when I actually called her myself and listened to the things she said that I realized that he wasn't lying about the threats she made. She actually tried to justify her actions by saying that her and my husband were just alike and that I just didn't understand. This has completely devastated our family & when I spoke to her I simply wanted her to understand that there was a true family involved, with young children and that she could have chosen someone else if that was her needs & she didn't have to intentionally go after someone who she knew would be easy for her. I guess I just wanted her to think about her actions for the next time she did this with someone else's husband. Instead she just said that she wasn't getting what she needed from her husband and that her & my husband were able to together. To see the effects this has had on my family & even my soon to be ex-husband is so devastating. His therapist is talking about having him committed for his own safety. Is there anyway that I can ever forgive this 'woman' for what she has done and her complete lack of remorse for the damage that she has caused? I can't even explain the anger I have when I think of her driving by my home where the children and I are and calling my husband to let him know that she is doing it & willing to knock on the door & destroy his family. How can a person like this even live with themselves & how can the rest of us come to terms that there are people out there like this? If anyone has any advice, I just can't tell you what it would mean to me. I would like to destroy her happiness like she has done mine, my children & our family. Truthfully I am consumed with anger, but not stupid. Any ad
