Just watch some romance movies and do what the guys do...am kidding...you might use that tho...but it matters on your age tho...I mean relationship is not a simple thing as you might think...you need a great emotional intelligence since women have complex emotions. You need to meet their expectations... expectations you might not know you should meet. I suggest that you spend a great amount of time just as friends. I mean, friendship is the place where you get to know her expectations and relationship is the place where you fulfill them to her. Get to know each other better. You might be too young for this but you don't want a relationship that doesn't lead to marriage. It is hurtful for both of you, especially for her. And you don't wanna hurt her if you love her. I am not advising you to decline her request, because 'let's be friends' might hurt her but create an environment where you get to know each other, be there for her, give her a great deal of time, attention, care, give her everything that you know you should give her, but also get to know her to know her other needs... I promise you that ladies might have greater expectations than you might need...b prepared to that... you might be everything you can be and that might not be enough...and the girls who read this, I do respect this character of you because this is what makes you mysterious and I love that...so dude this is my advice...if you wanna talk more, drop your username
