Dont try to change to please someone else. Love yourself, honor yourself, respect yourself, and be your own person, and someone will love you just they way you are!.....Unless of course your just a narcissistic jerk. Then by all.means, change!
If you date a guy long enough he'll start to sound like your dad when you were in junior high: "Have fun! Be safe! Call me when you get there! Don’t talk to boys!”
