When did all of this start happening? I will tell you this, the behavior she exhibited tonight is very indicative of rape. It's atypical of what rape victims will do. Is it like her to call for her mother? You are going to have to sit down with her, perhaps with your family doctor, or perhaps speak to a rape counselor, maybe even at some point the police may have to be involved. Maybe it's someone on the job that is forcing her into a situation, or something that happened when she was working late one night. Regardless of what it is, she has to come clean and tell you what's going on. The behavior she exhibited speaks volumes, but I wouldn't necessarily expect cheating, although if she feels extremely guilty about it, it could. She cannot go on with this type of behavior with the kids around, so, sit her down and ask her to come clean. Are you willing to forgive her if she did cheat? If so, tell her that. Please don't hesitate to respond if you want to talk more.
