If you are in a relationship, whether dating or married... Would you try to change your partner? Criticize him/her? If your partner criticizes you about your personality, appearance, etc.. would you feel hurt? Would you change for your partner, even though before he/she accepts you, he/she is already aware of your 'flaws'? As for me, if it's something constructive, like for example, the guy is smoking or heavy drinker, I'd try to get him to change, before I accept him. And if he tells me something I should change, I might accept it if I think he is right to say so.
