I would echo Sandi's point. As I said, I might give very different advice if you were not due to have a baby soon.
But you ARE due soon, and without concrete OW evidence in your face, (the kind you don't snoop for)
I'd just plan on seeing how much the baby moves tonight...
Also, with the benefit of hindsight, I'd say both parties in piecing must do IC, as well as mc.
Each party has to figure out their path thru, sometimes it's a lot easier to do without the spouse in the same room and sometimes it's easier for each spouse to have a T that is 'theirs...'and we need some sort of relationship barometers, not all about transparency but how "WE" are doing as a couple.
That EE workshop in Philly that I mentioned to you before-- (And our m was strong when I attended)...but I went alone first.
And because I attended alone first, I was much less inhibited without worrying about h's thoughts of my feelings.
I didn't edit my answers or rehearse my thoughts. I was free to discover things about myself. A good T can help you with that, and your h, no matter what.
Your h's indecision and present weirdness, IS a big problem. We get that.
I can only imagine if I had done damage to my family, how much harder it would have been to get MC with my h there too. Alas, your h is not here on this site now. Maybe someday... So, back to you. Plans for this evening are??
