You think a woman with her money (and she presumably had a bit of her own before shacking up with a very well paid footballer) really has to put “themselves second to everyone else?!”
Pull the other one. She had money and opportunity. If she didn’t want to stop singing she wouldn’t have had kids. Or having had kids, she had the money to employ nannies.
She had enough time on her hands to go swanning around the red carpet events with him, she launched several collaborations with other people, (which don’t seem to have gone too well, although that’s perhaps beside the point), and she had a presenting gig at one point. Not exactly the life of some poor, hard done by house Frau is it?
I’m sure there are plenty of single mums (and dads) who’ve found their choices a hell of a lot more limited than she has. Anyone is free to drop out of a relationship at any time, but she shouldn’t be trying to make it something it’s not, just for the dubious PR value.
