His_harley, I think adamgunn is correct. There are situations where couples live apart, but are still quite stable. It's uncommon, but it does exist. The whole point here is wondering how stable the couple is? Some swinging couples won't play with couples who aren't married for that very reason. You two fall into that category, unfortunately, We wouldn't have an issue playing with you since you've been together for ten years, but some would. Likewise, there's reason to potentially be concerned here. What you don't want is drama coming from this couple. If they're not very well committed to each other, there's the potential for drama. That's impossible for us to judge, and will have to be something you two see/feel for yourselves coming from them.
