Jer, my H said all the same things. (In therapy, etc.) It's an affair, it's not about "figuring out their head" or whatever nonsense they are spewing. You're probably right that she's traveling to see the other person. And you're also right to just let it happen. The more you resist, the more she is able to paint you as her adversary in her mind. Let her do her thing, and allow yourself to see her for the real person that she is revealing herself to be. Then ask yourself-- is this someone I really want to be with? Then get busy focusing on yourself and let whatever unfolds unfold.
