Can alienation of affection charges be filed in the following situation?
My husband and I are living apart, he in Illinois and I in Arizona.

He and I would speak on the phone almost every day until I went back home to Illinois for a suprise vist on Christmas Eve. When I got there he told me he didn't want me there and told me to leave, I was shocked. I didn't realize it but his girlfriend was there. Since then, he has sent me valentines cards, e-mailed me and talked about moving to Arizona with me. He had an airline ticket and had calle dabout several jobs in Arizona. I found out from a friend that he was still seeing this same woman. I called and left him several messages and told him I knew he ws still seing her. He then changed his phone number at our home.

My husband accidently forwarded an e-mail to me with her name on it.
I e-mailed her and told her we were trying to work things out. she continued to see him.

He recently started e-mailing me again and asked me to please be patient and we would be back together. After this I find out he has taken this woman around our grandchldren, to his families homes and she stays in my home (which is still in my and my husbands name) with him 3 or 4 nights a week. I know her name and license plate number but I do not have her address. She is still seeing him even after I sent her another e-mail.

Do I have just cause to file a lawsuit in Illinois?
