How do you cope, stay calm, and try to help when your partner is highly insecure (a product of previous relationships) and beginning to steam roll the relationship? The relationship started great, then his insecurities started to show, he tried to work on them, and has now resurface full force. We have lived together for almost a year now. I don't know how to help him anymore when he attacks me or becomes highly irrational. Neither of us are perfect and we are each other's best friend. Does anyone have any suggestions on how to respond or handle someone when they get to this irrational, lost breaking point?
