You can't change a person who doesn't want to be changed. It has to be on them to change for themselves, not for you. If she likes to party hardy all day and night, thats on her. You may like her and she may like you, but if its not working, you best to let her go. People have to want change and seek change in themselves so that they can become a better person. Its her choice. But don't get yourself caught up with somebody like that. Or else your emotionally investing in the wrong kind of person.
You can't make someone change for you, but u can make them realize what a great life they would have with a guy like you by showing them. Like show them how much of a great friend, boyfriend, husband that u would be. The right person will come along :)
Not many girls end up partying their whole lives. I think it is pretty normal for people to grow out of the party phase. But you don't know how long it will last, and she would probably resent you if you tried to stop her from having her fun.
