My Split Personality Boyfriend

Synopsis

My boyfriend seemed to have split personality. One second he would hug me and call me baby. The next second he turned as cold as ice. I reached my limit and started typing, [Let's break up.] But on a comedy forum I frequented, I saw a help post. It read: [My girlfriend keeps calling me by my brother's name. Is that normal? [My brother received the love letter from her, but I chased her. Now she seems about to break up with me. What should I do? [This is urgent! Any quick guide to getting promoted to boyfriend? Money isn't the issue. I mainly want to piss my brother off.] Looking at the familiar profile picture, I fell into deep thought. What kind of ridiculous move was this?
