Life can turn on a dime. It isn't fair, it hurts, but that's the way things are. And we want to hold onto the past because it's comfortable, it's what we know. But that's no way to live. You did your best and you ended up with someone who has very different values. Who knows why that happened but it happened.
Now it's time to shift your focus. This isn't a setback, it's an opportunity. Are you going to waste it or take what you've learned about yourself and see where those skills will take you? I know that can be scary - I'm in the same spot - but the steps don't need to be large. They just need to be steps.
This doesn't mean being happy about Ding; it means accepting the current sitch and transforming the circumstances of your life until it works for you.
