I might get lampooned for this, but IME women tend to move onto the next bloke to get over the last one as quickly as possible, whilst men, tend to be just p****d off and dwell....
I think the night out thing works less, the older you get, [having done that many hundreds of times] and the more times you've been through it, the harder it is to commit like that again, cause you know whats waiting.
It takes years and years sometimes.
