Miler, I completely agree with you about NOT changing behavior. 180s are permanent. Self-differentiation (detachment) is permanent. GAL is permanent (maybe not every night, but you should still do things outside of the house and with friends).
What you SHOULD change is the lack of pursuit. Once she is committed back you should buy her flowers occasionally. Take her out at least once a week on a date. Constantly fill her love tank with her love language! (I think you said it was quality time.)
Miler, one thing I would change when you get back, as long as she continues to make progress, is something called talk and touch charges. Please google them. I think once you are back from your trip you should start incorporating them daily. When my W started to make efforts I incorporated them to great effect. Go slow at first. The talk charges are great because they are hard to go to far with. But the touch charges you have to start small. A hand on her shoulder is you walk by. Rubbing her foot as you walk by her on the couch. Very small, short, almost imperceptible.
