Don't get me started on this.
Yes it should be 50/50. It's one thing when you are a couple, to have one person restrict their career and do all the childcare, to support the family unit and enable the other person to earn big, for the family unit. But when you separate, you both need the opportunity to earn. You both need a break. You both need to provide childcare. You both need to be able to socialise or date.
Yet one person (usually the man) goes, "fuck off love, you haven't got a job like mine, so you need to carry on looking after the kids, like you used to." Whilst ignoring that was only the case because he paid for everything.
I particularly like the men who make out their ex's are some kind of "slag" because they have a new man stay over. They walk round, chests puffed out, "around MY kids, don't you know."
Well, yes. If you ever looked after YOUR kids, then they wouldn't be there all the time, and she could have someone stay over without them there. It's you that causes her never to be able to leave the house in the evening without paying £60 for a babysitter every night. So, yes, she stays in. The five women you've dated, shagged, and dumped this year alone, are fine though, because the DC you never look after, are therefore never at your house to watch the shitshow.
