You should just be happy that she wants advice from you
and not some male friends of her.. who are not alpha like you, and will just lead her to the wrong direction!
She tells you everything, she trusts you.. and after being together for some time, you will know whats best for her..
you should be super happy about this..
Now give her the best advice you can give her
I'm currently trying to help my GF with her self esteem and such.. Cause she knows how chill, great, high energy, alpha, and confident i am.. if you are like that too, got good inner game... Well, you have all of the tools you need to help her!.. Even with deeper problems..
