Shawnee-
I'd keep an eye out for him Shaw but I wouldn't be too nervous. Like you said, he didn't love you, and you didn't love him. If I were you, I'd stop talking to him entirely for awhile. When the cell rings, don't answer it.
Your marriage has nothing to do with it. He's just trying to hit you with anything he can, don't let it effect you.
Once again, I am proud of you!!
