Am I Hacked?

[brandibug]

So today, my fiance (who has unlimited access to my computer in case I need help) TeamViewer IMed me. He sent me a couple of messages:
"Do you want water?
/awkward silence"

Then after that he couldn't message me any more. We were in the same room, and he informed me. So I messaged:
"Test?"

He saw that, and replied "How is this working?" I didn't get it, we gave up on it. When he went afk (away from keyboard) for a moment, he got a message from my account:

"NO THIS IS NOT WORKING." And then he saw that I had blacklisted him. I never log into my account for IM purposes (I don't know how). He always IMs me. So I didn't blacklist him, nor did I send the all-capped message.

I attached my and his log (named appropriately), and mine mentions encryption at the end of it.
