Thanks Kimmy.. I think I'm just scared. Do you have any advice on a way to tell her that might be easier and safer for her?

I'm thinking of driving there, sitting with her, and then telling her how I cannot be the guy in the pictures anymore no matter how hard I try. (She recently got pictures of us from years ago when we were happy.) I'm also going to give her a couple crisis hotline numbers in case she gets out of control. If it is bad enough I might call one and see if they will call her. If she threatens an attempt, I think I'll call 911... Problem is, I had to call 911 for her a long time ago and then her family called me at work and yelled at me. Small price I guess....
