Oh, no, I understand completely, and I don't blame you. ;0)
I am just kind of amazed at this forum, and I don't really want to seem like I am lurking, so I joined to try and be as visible and up front as possible. The only exposure I've had to something like this was a co-worker who had an open marriage. Turns out it didn't work too well, the husband was having relationships without her agreement (she is bi). I suppose if you aren't agreeing on who is in the relationship, that's not too cool. She's with another woman at present. If they are open with the relationship, I don't know..
I may not post much, simply because I have never been in a relationship like this at all, so I may not have much to offer, however, generally, perhaps I could be able to offer a viewpoint from a traditional relationship? You think?
I have been married twice, first husband died, the second, we are still married, but separated, he lives in another state with his GF.
