MLC W and preparing for S or D in the new year

[Gordie]

Over the last 48 hours, W has been acting differently, doing her own 180s. She hasn't said anything and we haven't had any R talks, it's just a vibe I'm getting.

*About 10 days ago, I was getting the vibe that she was uncomfortable with our regular hello and goodbye kisses on the cheek, so I stopped. I didn't even know if she'd notice or if she'd feel relieved (maybe the kisses were pursuing). Yesterday, she started kissing me hello and goodbye.

*Today, she texted me out of the blue thanking me for something I did for her yesterday (she usually doesn't do this).

*Yesterday, there was the request to snuggle in bed (no ML) and touched me non-sexually, a lot more than recently.

Of course, I'm wondering what is going on in her head, but I'm not going to ask her. As far as I know, she is still full-steam ahead on the separation process (though I have not yet gotten a written proposal from her/her lawyer). Why is she acting this way if she is at the same time plotting our separation? And what do I do if she says she's having second thoughts?
