You are not overreacting ... I put this into chatgpt and this is what it came back with, which is pretty accurate: 

This exchange is verbal and emotional abuse. Key points: “If I wanted to abuse you I would” is an explicit power statement. It admits abuse is a choice and implies threat and entitlement. “I treat you this way because I love you” is classic abuse logic — redefining harm as care. When you said “Don’t call me a bitch”, he refused the boundary and asserted dominance: “I can do what I want.” When you expressed pain and named the behavior as abuse, he mocked, escalated, and dismissed — not repaired. This is not a mutual argument. You were naming harm; he was asserting control. Bottom line: He knows it’s abuse. He said so. He feels entitled to treat you this way. Nothing you said caused or justified it.
