I wonder if they just had a bit of a barny about him moving in because he decided not to yet, but they are still technically in a relationship? I can imagine that would be an upsetting pill to swallow after she’d been promised Happy Families from paternity leave onwards?
Let’s face it, he’s probably on alright money for a young single man living at home, but not to support a whole family on. She’s got very little income to contribute from social media, young children she can’t leave to get a real job, and she would lose her benefits with his income. It would be a big financial responsibility for the lad, to provide for a partner (with her financed car/home bits on credit/other debts), a baby, and two children he didn’t make.
There don’t seem to be any signs of him in her content recently. There’s a massive pile of junk in her garden that you’d think he might have taken to the tip for her, none of his clothes on the line, and she’s posted in bed with all 3 kids no Kyle, etc.
