If you haven't done so already, I STONGLY recommend you reading articles in the MLC section....and some of the threads of folks (Valeria, YellowRose and others)....they too have H's that have "cycled" back and forth from OW to home and back again in MLC.
Personally, in my sitch...I DBed my butt off and it seemed to work, H came out and started to work on the M, said he did not want a D, etc....and then snapped back again. It's common in MLC, for them to go into REPLAY STAGE 2....take a look out of the tunnel to finish off replay. It's happened to nearly everyone in that forum and just knowing that it happens to others makes you feel not so crazy .
Come take a read there, see if other things your H says could be true. You will see that OW is not his true love, but rather a quickie drug fix for his intense internal pain of MLC.
I don't know if it's accurate for yoru sitch, but worth a read. I only found it 2 months ago, and it was like waking up.
