I think Emma struggles with people being in her space, I think she panicked when it came to lockdown and Tim coming back from uni and support bubbles weren’t a thing untill June? I think because they’ve been together for so long but not always been in proximity to each other (as he was at uni) she sort of feels like she’s missed out on the living with your boyfriend thing. So panicked and was like yes move in with me, but now regrets it as he’s working from home and she can’t just swan about as she used too, I think she really struggles to cope with any change! She shouldn’t have had him move in
But on the flip side, it’s her flat, she paid for it (or the bank of dad did) probs is paying the mortgage so she’s entitled to decorate it how she wants, what she does need to do is get Tim some more storage etc!
