Ive been in a relationship with a sweet and caring guy for 5 months, but he has difficulties with defensiveness and shutting down during arguments. He often brings up past experiences as a justification for his behavior. After two arguments i was the one to initiate reconciliation, we both established boundaries regarding meeting friends of the opposite gender without prior communication. However, when he was about to meet a female friend without informing me, he disregarded my feelings about breaking the agreement, resulting in a breakup . what should I do
