Toxic Relationships are destructive to the soul. Never doubt you did the right thing.
Free advice and worth every single penny; Cut off all communication, text, e-mail, Facebook, etc.
People like that have a tendency to never go away. They crave a response, any response, even if it is negative. The secret is not to respond no matter what; never, ever, never. Eventually they find another victim for their poison.
Stay Safe and Good Luck
