Why do girls tell nice guys not to change?

A friend of mine that I really like was complaining about how she can't get a guy, and guys don't think she's pretty, or they just use her, etc. I told her I was there for her if she wanted a nice guy, but I know she doesn't like me and I acknowledged that nice guys typically aren't what girls are looking for. Later I asked her why that is and got the usual answers, they like the challenge, want to change them, etc. So I asked her if that meant that I should be like that and right away she says ';NOOOOO you're nice, don't change yourself.'; I don't get it though. Every girl that tells me I'm nice like it's a good thing would never date me, but then they tell me not to change. Why do they say that? Do they not want me to be happy or something? I'm not good enough for them the way I am, but they tell me not to change. Why? And not to be conceited, but I'm not ugly or anything if you thought that had something to do with it. I'm in college if that helpsWhy do girls tell nice guys not to change?
People can't usually put a finger on what makes them attracted to someone else. I don't think that your niceness has to do with her not being attracted to you, since your niceness is definitely a positive point. She probably honestly does not want you to change yourself, and wants to be a friend, but just doesn't want a romantic relationship now.



And just because she doesn't have romantic feelings for you doesn't mean that other girls won't. It's just a generalization that girls don't like nice guys. It's a really illogical generalization and I don't think it's true. You're a nice guy and she's a good friend, so don't change that.Why do girls tell nice guys not to change?
Girls need the nice guys as a shoulder to cry on when the bad boy rips their heart out. You help make them feel better so they can find another jerk. Rinse and repeat. Ask your friend about this. She will confirm it. Maybe not willingly, at first, but she will admit it is true.
