you don't just find a boy. you have to get to know them. not "oh I've know you for 2 weeks, and I like you" I mean like months worth of a friendship. great things take time and patience. just wait until the time comes
One more example: you and your friend are looking for your car in the parking lot. You want to say 'I see yours but not mine. ' The possessive pronouns you need are 'mine' which is mein in German and 'yours'which is dein in German.
