i feel really happy because of what from many members here

^^
thinking about most of the serious replies, if you really like her, be who you are, don't try to follow your mates, like, mostly, ur mates from school, whenever u meet a girl and like her, they try to make you rush things, and try to make u be a player, and try to make fun of you if you keep it cool and smooth, and get her "decently".
It all ends up on what kind of relationship u want, and how u like the girl tho, imo.
If you really like her, follow what most of the "serious replies" say.
Just be genuine with her, and yourself, but remember, you "always" have to be a little player, when i talk about beeing a little player, i don't mean lieing and dirty stuff like that, aka treating her like an object, etc. I mean, keep it "cool", don't get a brother and sister atmosphere going on, otherwise, it can get tricky :/
keep it a lil "sexy", cause, if that she just "likes" you, and not truly loves you like for real ever and ever bajangles.. she can get bored/get interested in someone/something else fast. Cause nowadays, things tend to be too phisical, so, if you can come on strong both sides, and if you can be a great "lover", and a great "friend" at the same time, you'll end up being a great "boyfriend" and she'll have a tendency to always like you more

idk, just some random thoughts about the situation going through my mind
