It is ac tually common for us to return to dysfunctional relationships. I totally get where you are coming from. It happens so slowly sometimes and we have reason to believe they have changed. It is part of the cycle of abuse, "the honeymoon period" they call it. It usually happens right before an escalation of abuse . It makes it even more confusing for us. What did we do? We must have triggered it bc they were being so nice a week ago.
It adds to our self blame , abusers know that and what they are doing.
don't blame yourself, ,it's never your fault.
Glad to hear your focusing on yourself
