What the heck am I doing now???!!!!

my sitch.
M 26yrs.
H with OW , bomb dropped 10 months ago, probably EA & PA for over year
Trying to be a good DB'er now for months with some babysteps:

But--
Ran into a little problem recently, or is it a problem? My H and I over last few months have gotten to be more relaxed and much less tension at home now. H does not live at home, and also does not have his own place. He is a wandering nomad, between jobs ( firestation) and OW who lives several hours away. H now comes home maybe 1 or 2 nts. a week.

As of 2 weeks ago we had seperate BR's, but had sex after 10 months. Kinda just happened, tender and intimate, but quiet and no R talk from either of us. I know the OW still in the picture. Couple more episodes followed this one and now we share same bed. But I see no other changes in him. I am finding it so hard to keep my expectations at zero after this! Any others ?

Also not sure how well this is for both of us. No matter now tender and close it seems, there is this big OW in bed with us too. I mean I think me tonight, OW maybe tomorrow, Me this week, OW next. What am I doing to myself! Pretty hard to keep quiet about R, but I am. My "friend" R with H has a whole new turn which I am not sure is healthy. No, I know it's not, but not wanting to give it up. This was an aspect of our R that played a big part in our disconnection.

I really could use some guidance.

So now what? I have been trying to keep my expectations at 0 but the head has a hard time telling the rest of me this after last couple weeks. H remains very quiet about "us" and still very much in his MLC. Would love to hear others who found themselves here as well.
