I have never once dated a man that expected me to me 'perfect' whatever perfect means! You are dating the wrong men if they make you feel that way. There are men that don't make women feel like that - get one of those - top of the range men.
Well I have been with the same bloke for nearly 20 years and when I was dating there was no social media so things are quite different now I think. I don't know, I think I am also projecting a bit because I have pre-teens, a boy and a girl, and I am pretty terrified about the world they are about to navigate!
