Definitely! You start smiling all the time and thinking positively. Apparently you also start glowing because of how happy you are. You also start thinking in terms of two people instead of just for yourself. It's a real personality change.. and for some reason it feels right, even though you are changing because of someone else.
Aawww, thats cute.
Sometimes when I'm supposed to be having a serious conversation with someone, I remember something my hubby said and start smiling, other person gets really confused though!
