yes provided she really isn't under the patio, you feel there should have been some communication between rob and jess by now. not necessarily about whether to initiate divorce proceedings or whatever, as i guess it's been only a month or so since she left, but she might need some of her stuff, and if she hasn't taken up the new job (presumably she would have done by now if she was going to??) they will have to talk about money though obviously her mum is providing food and shelter
i've forgotten about whether rob has said if he's told jess about helen or not? wouldn't helen be curious about arrangements with jess (finances, divorce)?
