What Does This Mean in a Relationship?

I think there's a lot of analysis. I'm always trying to figure out what does this mean in a partner or in a friend. What are they really trying to say? They're thinking about it the whole time. Maybe I sent a message that was misinterpreted. Maybe my partner is mad at me. It's like this busy mind work that is exhausting. That's all the work is to not get rejected and what we see in a fight is a rejection.
