Girls don't want to be anything more than friends. What am I doing wrong?

Im a sophomore in college as well. The exact same story you stated above cannot be more true with me. Getting friend zoned sucks and it puts you down at times. The only reason i can say that I'm still singe in my life is from the fact that i don't go to parties and drink or do drugs. If you're not drinking or partying at college much then you're not introduced and socially around many girls. Outside of this environment you do not have many opportunities to meet new girls unless you want to be creepy and spot up a random girl on the sidewalks at your campus. I would recommend joining clubs or organizations getting more chances to see girls you share common ideals with and hopefully open up to ask one out.
