Not really a relationship thing directly although it does affect my relationships now!
I never grew up with parents after the age of 13. Abusive stepfather etc etc. So In terms of positive female role models I only had one, my nan, but her views were understandably out of date. I have noticed now thanks to mumsnet addiction that my views as a woman are starting to come into their own and solidify.
What I mean is things in my head seem much more well rounded, assertive, fair. For example being aware of feminism and my right to be treated equally. Challenging unacceptable language in a polite way. Just being more self assured and assertive, but kind. I'm probably not explaining this very well!
I guess I'm trying to say thank you that mumsnet, as a collective, through many many threads etc, has evolved my views and been, effectively, a positive female role model. At the grand old age of 28
