Maybe the way he is behaving right now (and it isn't a kind way to treat someone) doesn't mean anything about my value as a person. Maybe I can be compassionate with myself about where I am.
Maybe hoping for a better future, doesn't imply a better future together, but a future where I feel peace.
I think you nailed it. I'd drop the "maybes."
You have value as a person apart from anyone else who explicitly or implicitly says otherwise. Additionally, you can give grace to yourself though I know that's hard. It's necessary and right.
