Toxic people will hurt you and then try to make you feel bad that you are mad or hurt or upset. It's known as blame shifting. Instead of taking accountability for their own actions, they blame you got "having feelings." Abusive people do this
You are allowed to terminate your relationship with toxic family members. You are allowed to walk away from people who hurt you. You are allowed to be angry & selfish & unforgiving & don't owe anyone an explanation for taking care of you.
