Love doesn't hurt.
People who truly love you can hurt you badly.
The problem is not if they love you or not...They do.
The problem is that insecurity, hatred, and fear overtake them and cause them to hurt you and regret it later...but you can't fix them. Only they can fix themselves.
You need to create a safe distance for yourself to not be hurt again which may be no contact at all.
They need to resolve their issues and gain control over their emotions. You're not abandoning them by taking care of yourself. You're preventing them from doing harm.
