So sad this has happened. Sounds like since she suggested you just talk to Sean, that somehow he did not like the idea of the slight change of plans for whatever reason and is either using it as an out because he really didn't want to go, or is just being childish. Sounds like she's a bit tired of dealing with it and that is why she suggested you talk with him. We never know what is going on in someone elses house. I'd probably call and make sure that they are really calling it all off, and then let it drop. Sounds like there's more going on here. It may not be about you at all, and may be a control issue between them. Probably best to just be there for her should she need you and try to plan another outing of a different type at a later date.

Hope all goes well this weekend!!
