If I were you, I might consider contacting RT one more time. To apologize for blowing up at her. Tell her that your H is more than free to join her under the stars if that is what he wants. Then end the conversation and say goodbye.
Why apologize? Because then it makes you the better person that you truly are. Why tell her H is feel to go? Because he is, and we all know he ain't goin' nowhere! (but don't tell her that!)
You may even want to apologize to H, (separately) and then hint that maybe it's time he makes up his mind here.
Why would you ever apologize to the OW/OM??! S/he is not in the marriage. Don't even dignify or acknowledge her presence much LESS apologizing to her!!! She is a homewrecker who knowingly engages in H in their Skype sessions with the full knowledge that he's a married man and even encouraging him to divorce you. And even had him fly more than 3,000 miles to spackle her kitchen...yeah, yeah...right!!! How crazy is that??!!
