I don't know. Obviously I originally thought that he was having an affair. But now I don't believe he is, we have joint finances and I see everything and we're in contact a lot. I feel like this flat is his cave to go lick his wounds, work out what to do with his life and have a shorter commute to work (his job is brutal enough without the commute, though I have always reminded him that it is his choice to do this job). I also felt like this flat was a temporary thing. He hasn't bought very much stuff for it, it's furnished and he has sleeping bags for any guests staying over. Given what a shopaholic he is, that seems like it's temporary to me. But he won't let me go there, I've stopped asking him now. Maybe I'll never see it. Maybe the next positive step is he asks me to see it and I spend time there. I don't know!
