Total bullshit, but sadly seems reality.
It is why so many men very quickly line up a solvent women with low self esteem to do the parenting that they want to avoid.
From what I can read their loyalty is always to the ex partner and using their girlfriend as free childcare for the both.
Total mugs game.
My friends daughter was a teacher and the first summer they moved in together, he assumed she would be around to support them during the holidays.
She had made holiday arrangements and told him she wouldn't be around at all.
He was genuinely shocked, and pissed off.
It was the wake up call she needed.
She went away for the summer and moved back out again.
She had zero interest in having children in her late 20's nor being free childcare for anyone.
She had been very clear on the children point but apparently he thought she'd still be up for free childcare.
It was a useful experience for her and will no longer be open to men with young children.
