Manley is, in his own way, a fantastic father to his 2 little girls but the way he speaks to Mia, and the way he dismisses her as a Mother, isn’t fantastic at all
and Marliya is too young atm for any of this to truly affect her but it won’t be long before she’s not and so his terrible ways needs sorted pronto and it may well be that, in the end him appearing on television may be the catalyst in him getting therapy, on his own first, so that he can be totally honest about everything he’s feeling etc, etc, and then he can concentrate on lessons in anger management and how to just move forward in a positive way (I’ve been watching way too much reality tv lately
) with Mia, Marliya and co parenting.
Surely to god Erin can see that Manley’s treatment of Mia is because he’s bitter about losing her?! I think Erin needs therapy too about her poor choice in men due to, no doubt, her own childhood issues, she’s clearly suffering from low self esteem and doesn’t know her worth, it’s surely the only reason you’d put up with Manley again and especially after the way he treated her the first time around, I mean ffs she was a baby herself and she gets pregnant to a guy whom she thought loved her and then 2 months before your due your first ever baby, he goes back to his ex and gets her pregnant
and you find this lovely piece of info out on the day that you give birth
and you then have to get over it basically, get your strength back and move on...but we all know what happens after...
I actually genuinely feel bad for Erin and I’ve been negative about her in the past but it’s not that she’s desperate or has no self respect, it’s because she feels like shit deep down and Manley is to blame for this. 
It’s shocking to see how much bad parenting can damage a person well into adulthood and it definitely sends the message out that you really really have to think before you have a child to someone, he may be sexy, great in bed, funny etc, etc, but it doesn’t mean that he’ll make a good parent by any means
and a guy like this is ok for a non committal, non conventional relationship but not for babies and playing house etc, etc
Btw I’m not saying Manley is the guy that I described as above,
I’m just saying that the first serious boyfriend you have, doesn’t have to be the father of your kids, you have to kiss a few frogs first
