I'm not a fan of girls taking relationship advice from other girls who can't even handle their own relationship.
Why would you think that? Is there any kind of flaw in girls who can't handle their relationship?
Yeah, they can't even get their shit together.
No body is perfect, you should not judge other people. They might not know everything but maybe they went though the same situation and that is why they are giving advice.
You should never take relationship advice from other people because they do nothing but fuck up their own relationship.
There is a saying, "do as I say, not as I do" because someone can be very experienced but not execute it correctly. Don't you think it's not fair to judge them, because they can give really great advice. How about listening to it sometime, you might have an eye opener or learn something new!
