i feel bad for mia tbh, i think she's just so lost, in her first season she was desperate for a happy family life with the space raider, moving into a flat together, she wanted to get engaged and married, even though he treated her horribly, i think she really just wanted that happily ever after, i don't think she would've even left him if he hadn't ended it and moved back into his mums. But she was young and naive, and i think she's been trying to live her 20s with the carefree holidays, nights out etc whilst also wanting to be a mum and settle down with someone but it all gets too messy because its hard to live 2 different lives. yes she was way too forward with olly and wanting to move with M to Middlesborough so soon, but she was probably sick of southhampton and her past following her around, also the stress of her dad having cancer will have taken a ginormous toll, a parent being terminally ill is absolutely horrendous and i wouldn't wish it on my worst enemy, having to witness them suffer, treatment not working, bad news after bad news from doctors, i think once he started to get better she just wanted to run and leave her problems behind, leave the area, leave manley and his family, leave the bad memories. she should've thought it through properly but i think she saw olly as some sort of escape and saviour who could provide her a fresh start away from everything. shes a beautiful girl and i think she's got a lovely personality, i really hope she finds someone who is serious and she gets her happily ever after, after all.
