agreeing with Magdyln here. Easy does it..
It's so great to hear things are going so well. Remember though, NRE lasts up to a year and longer. The realy dynamic of your relationship is yet to come. You are making a good start for sure, but just enjoy it right now.
If you do a tag search for "moving in" there are some really good threads on the topic. Our tribe really went through a process with it and got some really good help from this forum. We took it slow and after 18 months or so we made the move for him to move into the apartment we have in the basement of our house. Both he and I have written extensively on this in various threads. I wrote about it in my blog too. Please feel free to PM if you have any specific concerns or just want to talk about it.
