She sounds unstable at best and hopefully she is not a "bunny boiler" (Fatal Attraction).
I actually mentioned this to my H too, I know I talk to much, I discovered a lot through facebook and I was under the opionion things she was posting things to him through her status updats even before I knew about the phone calls. On the day that I saw him on the phone for the first time and he hung up with her then spent the entire day with me at the football game she posted how f'n depressed she was, the socre of the game and then a website full of poems(written after the supposed rape) about how she wanted to kill people who called her a who*e and blow up work ect. The poems were 10 years old but she felt the need to post them on that day. At the point he was still denying anything physical had happened with her I had him read them and asked if he thought that this person might hurt his daughter or I.
