If you’re overthinking it, don’t act on those thoughts
There’s one dangerous and common thing that can happen after leaving a bad relationship: a person cannot get their mind off of it, which can lead them to think “Maybe that’s a sign I shouldn’t have left that relationship.” But, no. That’s no such sign. Your mind just has a tendency to ruminate on events surrounding grief. “Oftentimes people experiencing a break-up go through a period of grieving. During this grief, individuals could develop obsessive thoughts that cause them to ruminate on their relationship,” Matthews says. Translation: just because you can’t stop thinking about him, doesn’t mean you should call him.
