How do I romance a girl?

Hello! So I'm Law and I'm 15. I recently mustered up enough courage to ask a special girl to be my girlfriend. Contrary to most girls beliefs, I'm not a douchebag who thinks with their penis and plays COD all day. I really do respect all women and I think men would be nothing without them. Anyway, I've been thinking about doing sweet stuff for her that I've always wanted to do. Like hold her hand, give her my hoodie, hug her from behind and around her waist, tell her she's beautiful, and send her good morning and good night texts without being clingy. Should I do all of this. If not, what should I do, and if so, what else should I do? Thanks!
