In all fairness it's a lot easier to keep a house looking nice when it's a new build and you've got all of the brand new fits-right-in-place furniture etc. My house looks scruffy compared to Chloe's but it's definitely clean and tidy and safe, it's just not perfectly finished like a new build is nor was I able to borrow money off of my family to have nice flooring and the best looking furniture, and my OH has lots of "stuff" (records and players, guitars, memorabilia etc) rather than just a ps4 that slots neatly into a tv unit. Amber's house has always looked minging, Megan's looks like it's lacking storage space and is full of small children's toys but it looks clean enough, from what I've seen.
I don't think the show at all shows Chloe growing up and maturing. It shows her being arsey and nagging at people until she gets her own way then everybody pretends she's right to save the argument. This has happened with her mum, her auntie, Jordan's mum and Jordan.
Chloe reminds me of my ex and living with him was hell on my mental health. Her mum seems like absolute gold but it's like she treads on egg shells for fear of upsetting Chloe. The way Chloe speaks to her and the things she says sometimes is awful.
