I think the only time she's looked really happy is when she was with Pete.
Others will disagree but, imo, he is the true love of her life and she will never get over him. Every ridiculous stunt she has pulled in the last few years has been a reaction to him daring to leave her.
I agree with this. But Pete had a lucky escape. God knows he's out of the KP mire but the poor kids have no choice. They're left with it with a succession of uncles. Kev will last a couple of years, then there'll be another 'uncle' and KP might manage to squeeze out another sprog before it's too late, then there's adoption options. Gawd help 'em all.
