Heehee, RP on safari.
On a more serious note, from what I gather you've been holding your needs in check while PN has been busy being emotional about roly, good and bad. You've tried to be there for him and you've been making a superhuman effort to make things work well in your house, but along the way the things you need keep getting shuffled to the side, tucked further and further away from being dealt with.
I think it's completely normal and healthy to desire your own space, especially if the space that is supposed to be yours is not a place where your needs can be met.
Taking this time to acknowledge your own needs will be amazingly good for you, and good for PN too, because if your needs aren't getting met, then you can't be available for him. I hope you can snatch some of the solace you need from your temporary digs.
