That was absolutely my thought process, meow. I couldn't talk last night but responded to a quite business-like email he'd sent a couple of weeks ago talking about estate etc. He had said in that email if we wanted anything of hers we should let him know. I already have specific things that she gave me before she died so I hadn't responded but last night I suddenly realised that his 'disposal' of her page (and it can't have troubled him too much - he wasn't friends with her as he only created his account after she died) might mean he could bin stuff without checking with us first. I was very polite and requested that anything of hers such as clothing or papers she had written be hung onto until we have had a chance to see it.
I wish I knew how to negotiate with him. He is so... absent.
