The opposite of unconditional love is toxic guilt. Toxic guilt arises from conditional love where someone will have you fit into a pre-determined template of love that demands that your behavioural patterns align with that template. And where you don’t, you’re not afforded understanding or having space held for you ; your non-conformity to expectations is interpreted as intentional and malicious.
Do not accept it or be tricked into thinking that this person was legit hurt. Their ego was hurt because they suddenly felt a loss of control. Whatever loss of control conjures in them will be automatically put on you as if you caused that distress and inner turmoil (when in actuality they stem from lifelong core wounds they never want to face).
