Today's lessons, boys and girls:

If someone treats you in a similar vein as those you know to have been dangerous to your emotional well being?  Best to let them leave your life as quickly as possible.

Learn your lesson.
Remind yourself why you are letting this person out of your life: Be your own champion and don't play victim if they walk out.  If they left before you could get rid of them?  Count your blessings.

It may hurt in the moment but believe me when I tell you that the pain will pass and you'll be better off.
