There are characters in movies who I call 'film characters.' They don't exist in real life. They exist to play out a scenario. They can be in fantastic films but they are not real characters what happens to them is not lifelike.
I'm friends with a lot of my exes but it took time. We didn't just get into it. I don't think you can be friends until you're cool with them dating someone else. That's when you know.
