I think she has been on a downward spiral since moving in with Benji, but I think it has all got a lot worse since his Dad moved back in. I think it has affected her a lot, caused her to be a bit manic- depressive ( sorry if that’s not the correct term) hence the constant buying of tat and obsessing about holidays. They go away so often, seems a bit unusual for a loved-up young couple with their own place, but obvious now that they are trying to escape his Dad! She feels that she is no longer the independent boss lady she tries to portray, as she is basically a lodger with no say over the house. Wonder what a tantrum she had to pull to get to keep her office rather than turn it into a lounge!
