Also, Ant's new squeeze seems to have started a new life pretty well - and seemed to have managed it as easy as he did. Also, his ex has a new life too. Do people think she is sitting there crying into her cornflakes at Ant moving on and him and his new wife having a baby? She probably doesn't care!
Also, it's farcical to assume it's easier for men to start a new life after a break-up. Of course it isn't. If you split in your mid 40s, it is hard for men AND women. Many women that age and older don't take any shit from men, and they are more fussy about who they date (and quite rightly so!) So, many men struggle to find anyone to put up with shit and their lazy-ass date.
The only thing that is easier for men (at 46-47+) is having more babies. But the vast majority of women I know do not want to have any more babies past that age anyway. Purely anecdotal, but yep, I can't think of a single woman I know right now over 46-47 who wants kids/more kids. (And that is women who have them AND women who don't.)
