Happiness?

What is the meaning to being happy? How do you know you are truly happy with where you are and who you are? Every girl wishes more that one guy who will be the sweetest to you and care and love you and cherish you cause he know you are the best thing in his life! I want to know what gives a guy courage and what does a girl have to do to make a guy come up to her and say "I just had to speak to you, because I know this may be my last chance". Every girl wants this, I want to know what makes a bad boy act like the most caring and loving guy in the world when he is around you! I cant stop thinking about him right now :( I want to see him and I want him to smile when he sees me and know that I'm the only one for him, but this is all a dream, a fantasy! Its not necessarily that I want a boyfriend when right now because I'm lonely (well maybe ;) but I want a boyfriend to have the experience, experience all the good things and the bad because to me I have always imagined going to high school and experiencing dating. All my sisters did and I feel like I haven't which means there is something wrong with me, i always thought having a boyfriend is what happiness is but i know that cant always be true but i just wish for that once, to experience it because when i leave how will i know how to do anything? :( but all I can do right now is wish and enjoy my single free life I guess :/
