I'm just concerned that something might have happened to her. I'd never do this to friend. I know her ex for many years, and I'm not really in touch with him. I even told her that I will not compact him.

These are her last messages:

If he knows u r coming he likely would want to see u?!?!
I just don't want to personally interact with him after all that ugliness.
I don't want him to know anything about my life.
He'd surely try to pump u for info if he knew we were in touch.
He's VERY manipulative.

I'm very sad if she stopped speaking to me because of that. I really loved her friendship. Maybe I should just cancel this trip.
