My wife appears to be through the crisis and is pretty normal now with everyone but me.
This is the deceptive part of MLC. The MLCer appears pretty normal to everyone but this does not mean they are through the crisis. If it is an Midlife Transition ie no PA with OP but replay behaviour with most of the other stuff - then yes that is quicker.
However the MLC(T) er will appear normal but to you who knows her the best - she will not be. And this is the sign that the MLC(T) is still in play and so the crisis has merely abated rather than gone.
Reconnection is genuinely reconnecting and not appearing normal. There is an effort to behave differently and to change the behaviour rather than reverting to "normal" pre BD behaviour. And the spouse is the last person to reconnect with.
The crisis is only "gone" when the MLCer has genuinely acknowledged their behaviour, apologised or become accountable for their actions because then invariably it won't return.
