You and John were fighting,, after seeing him flirt with Karen again you just didn't feel like holding back your words - insults and harsh words spilling from both of your lips in a heated fight,

"God I don't even know why I came back to you, you're just a bitch!" John said with an angry tone of voice, well that's new. He never called you a bitch, not once. And John didn't seem to care about it, most likely drunk.
