When you talk about a group setting, are you referring to group sex or doing social activities as a group? Is there some reason why you feel your partner's other relationship should always involve all three of you? It doesn't have to, you know, although most people would probably recommend a respectful acknowledgement kind of thing. But you don't all have to do everything together all the time... is that what you're asking? I'm just not clear on the question, I guess.
The world opens up... when you do.
