After our first swap experience, my husband was the same way as far as being extra attentive and "emotionally needy."
Not that I mind my husband hugging me and saying nice things to me but after a day of it, I asked "what is up with you? Why so extra adoring?"
So I'd say you're not alone in your reaction as long as it doesn't develop into a jealousy issue (and by the sounds of it, it's not).
Ride it out, there's absolutely nothing wrong with appreciating what you've got!
