Mhwag, it's still babble. The alien is still in charge and there's no sense expecting logic to come out. It just isn't going to happen. Plan A doesn't provide instant gratification; it's a process that works gradually over time. The four months you have to go in Europe is a long time...plenty of time for the plan to begin to take effect so try to stay patient.
The trust nonsense is something that comes up in most of the threads out here. "I will never trust you again,"...because you exposed his adultery! Normal human beings have an immediate reaction of "HUH?" but to aliens, it makes perfect sense. All you can do is chuckle (silently, to yourself) and babble right back at him. "Gee, honey, I'm really sorry your affair makes you not trust others." How does that sound? It doesn't make much sense, right? It should be perfect for the alien.
BTW, have you read Orchid's thread on reverse babble? If not, here it is:

He's decided to take the bills to himself, all he wants to share is griping about them. That's not a good deal and you don't have to put up with it. How about letting him know since he took that away from you, you're not interested in hearing about those bills any longer. They are HIS things now, not something for the family as a whole anymore. Instead, for a date, tell him you're in the mood for wiener schnitzel or something. If he can't make that happen, tell him you're going to go out on a dinner date with friends/kids/whoever instead...and do it.
The fatigue is part of Plan A, sad to say. You're working on yourself, making yourself a more rounded person and more attractive to WH, but it's enervating. You feel like you're on stage all the time and you can't mess up any of the lines and that's a strain, I know. In
Surviving An Affair, and various threads out here, the rule of thumb is to terminate Plan A when your energy, and love bank, get so low you can't do it anymore. That’s going to be different for each BS out here. I’d like to see more folks comment on this. We need more ideas. Hang in there, Lady. Don’t let the alien babble get you down.
