do you think she is telling him?

I recently connected with a girl who I knew in college. She is married with 2 kids to a guy who can not get it up anymore. We started chatting and talking about our school days. After about a month of talking on the phone, she told me she wanted to meet me in a motel. I mean I have not seen this girl face to face in about 10 years. So, I told her lets meet for lunch ( I wanted to see if she got ugly) and we agreed on a place. Well, one thing let to another and she wound up sucking my dick in the parking lot of the diner we met at. Now she calls me all the time and some times I hear her husband just talking to her in the back ground( never asking who is she talking to). When she calls me other times ( I am guessing she is alone), she starts talking dirty to me and masturbating while I tell her what I want to do to her. My question is this. She wants me to fuck her, with no protection. She is pretty insistant on it. Do you think her husband know about this? Do you think she is trying to piss him off? What do you guys think?
