LIS please stay strong! FOBD is right in that every sitch is different and you do have to trust your instinct. Maybe simply letting him drive you to work is a good compromise. Chances are, he'll talk to you more during the drive. You don't have to be super engaging but at least he knows you are still semi-interested(maybe?).
As a guy, I would know that sometimes I test the waters to see how the W is feeling the R. If she isn't feeling it, I feel super rejected and pull back. I know this sounds silly but here's an example.
Say we're fighting or something. We would make up and things would be ok. During the night, I like to snuggle so I would roll to her side to put my arms around her. She would pull away or "seem" to be on the furthest part of the bed possible.
My reaction? I'd feel rejected and hurt - MY FEELING'S were hurt. She didn't want to be with me. That's what was going through my mind.
I would then pout downstairs and sleep on the couch.
Sure enough, the next morning, she would come downstairs and ask why I slept on the couch. I'd give some lame excuse because I didn't want her to know the truth. What I wasn't reading from her is that she didn't like the fact that I slept downstairs. Even though she didn't snuggle, she wanted me there when she woke up.
I guess the point of this is that it does seem that your H is letting a little of the wall fall down but you're staying strong and not letting him. I don't think it's a bad thing that you give him a little - heck, test the waters yourself. Let him take you to work (ONLY if he asks) and see what happens.
One thing I've learned is that you have to take a chance even when you're detached. I did and it worked out (so far).
