I see so many people in relationsihps over thinking the situation. Why didn't he call yet? What did she mean by that comment? Overthinking can cause relationship mistakes.

What exactly are relationship mistakes? It's when you over-read a situation to the point that you say something silly or take an unnecessary action that turns off your partner.

So work on being in the relationship, rather than debating the entire relationship inside your head. You'll avoid relationship mistakes and have the best shot at making it work!
