My wife "H" (32f) met a woman "E" online around five months ago through a small social media group and they've really hit it off. Because H came out as bisexual later-in-life she has never had a relationship with a woman, and so I (33m) suggested we open our relationship so the two of them can date. I am happy my wife has found another person that brings her happiness and I'm working to find the best ways to be supportive.

E lives across the country so the two of them have never been able to meet in person. We are currently discussing her visiting for about a week this spring, however there are complications that I'd like us to try to figure out beforehand. I'll definitely be returning to this sub multiple times as we work through these questions.

First is the living arrangement. Our house is not large, although we do have one spare bedroom so it would make some sense for her to stay with us. However a week seems like a long time to be all cooped up in a house with the three of us, without a great deal personal space. I plan to try to get to know her by taking her to see all the sites, but still that's a lot of time spent with her girlfriend's partner. What are some tips to help E feel like she's welcome, but has her own sense of freedom in a new city?

Next, the "sleeping" arrangements. H and E are very eager to begin a physical relationship. However, our house is not large and I'm not sure how to both respect their space while making certain my own space is respected. I'd rather not be stuck upstairs for four hours while they get to know each other, but the only alternative I can think of is spending a great deal of time on long walks, at the movies, seeing friends or whatever else I can do to distract myself. Is giving up my space and "disappearing" at those times really my best option?

What other complications do you expect we'll have to learn to manage? Do you have any general advice?
