singleandfab yes, that was what i was afraid of, that a sofa date would turn into a sofa relationship! I'm not high maintenance at all, but I'd like to be taken out a bit!
However, he did kind of sound rather nervous about suggesting it, and mentioned something about it being cheaper... I suspect maybe he doesn't have much money because his arty commission-based stuff doesn't bring in regular income, and i don't think his interior design work does either. Which doesn't bother me, I don't care about his income. And he did offer to bring wine, and food, and romantic music...which sounds quite nice really. Plus, I admit i'd inadvertently encouraged any ideas of bedroom antics by indulging in very flirty/suggestive texting throughout the morning, which he instigated! Ahem! 
So, I rang back and suggestedt I go to his instead and bring the wine (nosy as to why he wants to come HERE), Turns out his mother lives with him! Poor chap was very apologetic about it, kept saying 'Is that ok, I'm sorry' and I'm going 'no, not at all, it's fine' whilst imagining endless sofa dates and always at my house. I sensed he felt very awkward on the phone so I just said breezily, 'Ok, see you tomorrow' and ended the convo.
I started doing the paranoid thing then...is he only looking for someone to visit for sex, etc? But then had a lovely text saying 'To explain a bit further, my mum is not that good socially in general. But I would like you to come over in the future. And soon, of course! She's very withdrawn and I'd like us to get to know each other on our own terms and in our own context. hope you understand xx'
Aww....I thought that was rather sweet, and I think he's being sincere. I replied that of course I understood and it was fine etc, etc, and he replied 'thank you for your lovely kind words and your understanding.You do me the honour of having me as your guest, so looking forward to seeing you tomorrow'...bless. Now I've gone all soft and girly about him again. I'm so fickle!
