I think the stories we tell ourselves matter. Maybe one of the things we need to do after we tell ourselves the stories a situation brings to us is assess, is the story true or plausible or does it adjust to reality? Am I telling myself the right story based on the information available and what others are telling me about the story I’m creating based on the facts available?

Of course, we can’t always corroborate our stories right there and in real time. And then once we talk to our partner(s) about the idea we constructed if necessary, of course is necessary to trust them. And maybe admit we all get jealous sometimes, but we can allow the feeling not to dominate us and take the best of us.
