I’ve never really thought that Olivia isn’t close to her family, but more that she just doesn’t talk about them on social media so much. She seems as though she comes from quite a well to do family with a decent amount of money and I’d imagine her peddling JP, dressing like she used to, sh*gging Wayne Lineker etc is just stuff they wouldn’t really want to be associated with.I'm not sure whether it's controlling or he just couldn't care less. Made apparant by the lack of support after her father died with him not even bothering to go the funeral, disgusting. She appears to be just an inconvenience to him now. Its very clear how she is clinging on to the relationship but there's just nothing to it.
It's probably because there is nowhere else to go and she has no life now outside of Sam and a couple of people she knows through him. She rarely sees her family. Her twin is clearly in a happy relationship and is getting married. She's only mentioned her brother once or twice so doesn't appear to speak with him. She also doesn't appear to have any friends back home.
I'm pretty certain their house they live in will just be in Sam's name, therefore without him she's left without anything.
interesting thought about Sam’s being the only name on the house though. That’d put her in a really precarious position if she’s stepped away from a big wage to start again and has no security in the house. Would explain why she feels the need to cling on to him maybe?
