First, define romantic.  You mean "be romantic' like try to have sex with her or try to woo her?  Because different girls want and respond to this differently.  I wouldn't try to be romantic to a girl I just met because I just met her.  I have no idea what she likes and trying to go overboard with candlelight, cards, flowers, songs, all that nonsense, seems presumptive to me.  She may hate it all and I lose my chance.  A first, second, and third date are getting to know the other person.  Those are not romantic, they're business set-ups, doing something fun so you two can talk and interact.  No movies!

If I had love at first sight, I'd be in trouble.  My wife would be pissed.  But if I weren't taken, I'd do something about it.  I'd go talk to the girl and introduce myself and go from there.

It depends.  There's no right answer.  Some girls want to be sung to.  Some girls want flowers.  Some want you to embarrass yourself in front of their friends.  Ask her.  And then do what she asks.  That's the ticket.  But it's all different.  There's no 'right answer' that covers everyone.  The most romantic thing I did for my wife, when I dated her, was get up early and scrap the frost of her car in the morning when there was frost.  She thought it was wonderful.

Sweet, nice things?  Listen to her.  That's it.  Listen.  Remember.  Ask questions and pay attention to her.  That's as nice as it gets.  It's not about the things you do or what you buy, it's about spending time with HER.  But she's not the center of the universe.  Remember that.

Woman's favorite topics?  It depends.  Everyone's different.  What are guys' favorite topics?  Mine are different from yours.  Same thing with girls.

You know a girl likes you when she talks to you.  That's it.  If she interacts with you outside of class or school, she likes you.  End of story.

Don't buy them anything.  Trust me.  Don't do it.

warmaker : Of course all girls are different, but I was refereeing to majority.

So not only are girls complex, so are answers to questions about them. Great lol.

Girls aren't complex.  They're easy.  I'd say they're sometimes easier to handle than guys are.

DO
Pay attention to her
Ask questions and remember her answers
Learn about what she likes
Smile
Let her talk
So no and disagree if you really believe your side
Let her talk to other boys if she wants

DON"T
Get presents and gifts for her
Hang around her all the time
Do everything she tells you
Stand next to her all the time
Be jealous of her friends and everyone else around her

Do those things and you'll be successful.  Again, there's no 'generic' girl and you can't expect the majority to really like one thing or another.  Guys are simpler so we can just 'like sports.'  But some really follow sports and can name 20 different college coaches (me) and some say they like sports but don't really turn the tv on and get into stuff.

Girls are all different.  Ask her what she likes.  Go from there.  She'll tell you the right answers to all your questions.  This is the fun of dating, learning all the new things the girl likes.

chryoyo : The most romantic thing i'v ever done is put the girls name on my boxing banner. 
The most romantic thing i think you can do for a girl is really listion to her,treat her right (don't go looking for sex), talk to her honestly don't keep things from her (presents and suprises excluded),see her for who she is don't set an expectations for her,Get to know her, Be there for her in think and thin, wether she is the prettiest or the ugliest , And when you get her don't stop romancing her don't stop makeing her feel special never let that flame die.

blasife :   I think I have my answer. Thank you for your help. Everyone. It means so much to me. https://www.vizzed.com/boards/thread.php?id=82798
