It's normal to give a visiting friend a tour of your place, boudoir

included, especially if he's renovating. Doesn't everyone want to show off their renovations? I do not think AT ALL he was trying to send you any kind of hidden message about larla. Unless he is the kind of guy who does that. But most guys don't throw subtle hints like that into emails.
Is there anything else about him giving you pause?
I don't see anything wrong with asking about larla, as long as you can do so in a non-jealous way.
I actually find use of the word boudoir funny in this context. I once looked at some thick red velvet drapes for my bedroom and a friend of mine commented it would befit my boudoir.
