Which is a better way to ask a girl out? (I'm a Girl)

Okay, i'm going to ask this girl out. I'm realllyy nervous, but I know she feels the same.
Should I text her and say:
Me: I want to ask this girl out, but I'm too nervous. Can I practice on you?
Her: Sure.
Me: Will you be my girl?
Her: Yes. Okay, now go ask her!
Me: I just did.<3
OR
Me: Can I have you?
Her: Have me as in...?
Me: Let you be my everything. Care for you, watch over you, make you happy, and always be there for you. I want to be yours and for you to be mine.

Well if your sure she feels the same way, invite her over to yours for a sleepover or something. Dont play these questions with her, just sit her down and discuss how you feel for eachother. Anyways, why would you become lesbian.

You should text her and tell her how you feel, I really wish I had the gutts to do that!! Just tell her everything.
Can you go to my page and help me?

And what if the answer to "Will you be my girl" is "mmm.. I'm not anybody's girl." in order to train your skills (you've asked her that after all). ;D I mean... these made up conversations... Come on, life isn't a script. :) Just relax and be yourself, talk with her, share with her, but don't be so overdramatic as in the second case. Personally I, for myself, wouldn't swallow so many cliches in one line. Doesn't mean you don't feel them, it's just too worn out.

i have to admit text one is cute but maybe just kiss her
