I agree with K18 that your wife is likely involved with someone else. Likely this someone else is also married. That is where your confusion comes from. The OM pulls her, she is then sure she wants to end things. When he pushes her away, she then wants to make sure you are still plan B. This is a very common dynamic at play with a cheating spouse that is unsure of their future with the OP.

The good news is that it changes nothing you should be doing. Get a life. Self improvements. Detachment. Those are your focus.

Stop picking her up from the airport. Stop being willing to help her with things like packing. Remember, she is firing you as her husband so stop doing the things a husband does. Also I'd end MC for now. She is using it to soften the blow for you and to ease her own guilt. Plenty of walkaways have said "we tried everything, even MC!" Just tell her "I've decided MC is a waste of time. I have a lot to sort out myself so will be doing IC instead."

Keep posting. We're here to help!
