Please remind of me of the counter intuitive DB principle to help me cope with H's mysterious activities. He says "he's busy" but won't explain. I'm sure there's no OW, but dropping hints about doing drugs (which he later said was only smoking pot - big deal) has got me freaked out. It's like the only thing that seems fishy is that he's acting fishy.
Do I just pretend I don't care and don't mention it?
Hope,
That's a tough call given the drug reference. If he's smoking and willing to admit it to you, he's probably doing more.
Since you have a little one, I think you need to keep a very close eye on your H's behavior. Not for you, but for the protection of your child.
Absent the drug issue, I think you are talking about a 180 (assuming your normal reaction would be to ask what he was up to).
