One skill I learned is to worry more about what happens in a relationship rather than about what may happen. E.g., if you text "I'm flying home on Jan-22", worry about how to respond to her offer, if she actually makes that offer. Some people worry about whole trees of conversations that never materialize.
To the question, I'd plan to go home solo, unless someone was really excited to pick me up.
I'm sorry she chose to use the space to get closer to OW. ((Hugs))
