What's really weird is that as I was leaving, H kept telling me to drive careful. This might not seem like a significant thing, but even prior to BD, H wouldn't have expressed so much concern. I live less than five miles away, so it's not like I was going far. I tried to avoid interpreting any sort of meaning from this, but about thirty minutes after I got home, H sent me a message to thank me for bringing the kids dinner. This was weird too--I always send the kids home with dinner, and I couldn't help but wonder if H was actually fishing for a response to see if I made it home ok. I took the bait, in any case.
I would just take his comments/messages at face value. Don't think too much into it. I've been there too, trying to decipher any little comments/movements that H made and seeing if I could figure anything out. usually there answer is no.
I'm happy for you that you had a great break with the kids. I'm focusing on planning all the fun with my kids for the holidays as well!
