If every person who liked it or shared it paid him £0.10 by Paypal or whatever, he could give the car away to someone who needs it and still have all his money back!
That's if the kid's his or not, 7months old means it's not like the kid calls him dad, but that doesn't mean there's any less attatchment/pain involved of course.
I don't get people who can cheat like that, dunno what I'd do in that situation but I'm quite arrogant in a self-respective way that I don't believe it would ever happen to me, but I don't suppose that guy expected it to happen to him. It's obvious the kid isn't his, most women wouldn't cheat on the father of their child (at least in the early stage of the childs life).
