She's the only girl in the school i like. The first to give me a chance. She slow danced and hugged me twice. Never happened to me before.I'm not a confident guy either.
Some thoughts that spring to my mind which may or may not apply:
Your class size will increase by an order of magnitude in college. the chance of only liking one person from such a larger pool is significantly reduced. Plus, there is a greater age differential that is considered acceptable, which bumps up odds of meeting interesting potential partners by another factor . This age differential factor increasingly works to your benefit as you progress through school.
True, the fact that older men with younger women is more generally accepted than younger men with older women gives male freshman slightly worse odds than freshmen women. Even so, odds are still significantly better than most High School situations.
Many people approach things in a try-and-buy fashion, or are simply out to enjoy themselves or "learn more about life and people" before getting into deeper commitments. There's an inevitable risk/reward ratio in meeting people. More likely than not, a match does not result (or only lasts a very short time) and one side experiences rejection. A decent person will try to minimize hurting others.
