I reckon she would say she gave up her job to be a stay at home mum and would take him for everything he has to offer. He would never be rid of her fully.I think Kyle is probably sticking around for the kids sake because these 2 have duck all in common. Noone wants their kids to grown up with separated parents, even if it's what's best. He's likely looking at it and thinking he's never home spending time with her anyway and gets to see his kids every night. Not in any way saying he's this great father, but it's probably for an easy life. And seeing how unhinged she is on Instagram, he'll see it a lot more so who knows what he thinks she might do. She could pull the I'm a stay at home mum, you worked all the hours so why do you think you should see the kids xyz amount.
Wonder if she'll spin that her mum just missed the kiddies so much since they moved out and then she wanted to help out as much as she possibly could so she moved in to help with things and then didn't want to go home...
Imagine the absolute hell Aimee would make his life if he was to meet someone new. He has to be staying for an easy life. Although with 4 kids and a teenager to support, god knows why he does!
As you said, he’s out working most of the time so probably makes it easier. But it's not a healthy way to live.
