LOL I refuse to get in a vehicle with my ex. We have 3 kids. I refuse to put myself in a place where I can't just walk off. Makes him furious!!
I also make sure to meet him in a public place or with wittnesses so we are never alone.
I'm actually quite scared of my ex and I hate to admit it. But you know meeting and talking on our own terms lets them realize they are not in control anymore.
