<human>: I'll try to make this as quick as possible. We started dating around 6 months ago, and we were great at first. We had no problems at all, and it seemed like we were perfect for each other. As time went on, we started getting into these little arguments more often. These little arguments turned into bigger arguments. The idea of breaking up came up twice, before I finally did it the other day.

I felt I had become super unhappy. Sometime during the relationship, I had stopped going to the gym. It was a big hobby of mine, and something I had enjoyed doing. I went from going almost daily, to not being able to get myself to go for one day. I lost 20 lbs, muscle, and strength. My grades were dropping, and everything in my life was becoming a mess. I never spent time with my family, or friends. I felt unmotivated at work. I don't know if this was just a phase in my life, or if she was causing these problems.

I started losing feelings for this girl, and I didn't want to tell her. She no longer made me happy, not like how it was before. She was really full of herself. She constantly reminded me that I seem to be getting too "comfortable". She told me about all the guys that want her, and how she has guys lined up wanting to talk to her. Super big turn off. We planned on going to Homecoming together, and three days before I told her to find another date. I broke up with her.

Before breaking up with her, I asked a friend of mine on advice. He is a little bit older than me, and has a lot of relationship experience. He told me that I shouldn't do it, and that I would regret it. I thought he was crazy, but he was right after all. I regretted breaking up with her the day after. I thought about all the good memories we had together. Did I rush to conclusions? Did I make the right choice?

Can you provide a brief rundown of the text in within 3 sentences?
