Why would you feel excluded? Are you also dating her lover? Or her lover's husband? If not, there's nothing happening there you could ever expect to be part of, so why would you feel excluded? (If you can't have any reasonable expectation of being included, it's just really odd to claim you feel excluded, I think.)
When speaking of various forms of non-monogamy...it ain't poly if you're just fucking around.
While polyamory, open relationships, and swinging are all distinctly different approaches to non-monogamy, they are not mutually exlusive. Folks can, and some do, engage in more than one of them at a time--and it's all good.
