I really want to date her.Pleases,advise..
Well, the first thing you should do is ask her out on a date. This will let her know that you're interested in her, and she can then decide whether or not she wants to date you. If she says yes, then you can take it from there. If she says no, that's okay too. Just be grateful for the opportunity to get to know her better.
Be clarified, mysterious, and respectful. Choose a private setting and try to notice these things, if she really likes you in that way, she must be dressing herself good, her hair must be open or looks stunning and she'd blush hard when you say a joke or something cheesy, she sure finds way to touch you subtly or doesn't mind you touching her on her shoulders or arms. But don't overdo the touching part as it may come across as a creepy over a long time without expressing your intentions. If that all fits then don't wait for long! Just clarify your intentions with her whether you wanna be friends or mingle together but in a very subtle way coz girls really do have a sixth sense on noticing such things & be a mystery to her and make her think about you all the time that'll make her go crazy about you! Good luck & enjoy!
