No longer together

I broke-up with my gf today. I told her in her bedroom and she wouldn't stop crying. Her brothers and sisters gave me the evil look but I didn't say anything. She asked me if it was because I didn't love her, then if it was because I found someone else, then if it was because she wasn't as smart, then she wondered if it was because it was my mom.

She called tonight almost within minutes of me getting home. I didn't know what to say. I know I'll see her tomorrow around campus again I wonder if I made the right decision.
