Listen, I don't know what bed you roll out of - but you clearly know nothing about psychology or women for that matter
If you think your wife is going to listen to her hairdresser for life advice - then you married a moron.
Your wife is not that stupid. Her hairdresser is "entertaining."
Before reality TV showed up - women went to the hair salon to listen to and watch the CRAZY hairdressers and they psychotic lives.
No women in her right mind wants to "emulate" her hairdresser. And the fact that you think she does --makes you sound silly.
The only people that can influence your wife is her "best friend" and when I say BEST, I mean the one women that she thinks is better than her. And women have a pecking order in their girl-group. The woman that everyone considers the "BEST" is the one that wields all the power. So if she says - you need to fuck someone other than your hubby - then she is going to consider it. "CONSIDER" not do it.
She will only take that first leap - if you convince her that you won't retaliate against her.
There is so much you need to learn - its not funny
