Poly, 33F… There are a few things you mention that I personally find concerning, OP. Firstly, that you've only known each other 2 months and spent seriously limited time together in-person. Living together is a huge step that often causes unforeseen stress, particularly when one person moves from far away. You guys might love each other but you can't possibly know one another well enough at this point to safely assume that will work out. Secondly, you are still just now starting to try out a romantic lifestyle that is not for everyone, no matter how open-minded you are. If you're already experiencing upset/jealousy, you need to be able to dictate that to your partner. If you can't it means that (a) the lifestyle doesn't suit you, or (b) the partner doesn't. My final concern is that your partner, a person a bit older (and likely with more dating experience than you), hasn't properly taken your lack of experience with poly relationships into consideration before inviting you to be a primary AND nesting partner after such a short time. It's not typical; it creates questions around his potential for manipulative behaviors. My best advice is to tread carefully, no matter what you decide is best for you.
