After I lost my memory, I forgot my scum ex

After years of deep love, my girlfriend lost her memory, and I was the only one she forgot. No matter how hard I tried, she couldn't recall our shared past, even treating me like a lunatic. Then, I overheard a phone call between her and her best friend, and everything became clear. "Memory loss, my foot! I just want some excitement, to see him squirm while I'm getting cozy with another guy." My heart went numb. I broke up with her. And then, I scheduled brain surgery that carried the risk of amnesia.
