<human>: Summarize the given text in a few sentences.

So to start off, this is somewhat of an update to a post I made in TIFU, regarding having a crush on my roommate and her seeming uncomfortable with her suspicions about it. Original post here 

Things since I made the first post have been going pretty smoothly. We're still hanging out a lot and become more or less BFF's. We've been roommates for 2 months now and will have to continue living together for 10 more.

Problems arose yesterday as I was talking to another friend on facebook messenger. I had vented a lot of details about my feelings for my roommate to this friend, and that day in particular I wrote about a sexual dream I had involving the roommate the night before.

Said roommate then wanted to read my chat log with this friend due to unrelated reasons. Normally I'm okay with this, she's read my conversations with other people before, we do share a lot with eachother, but for obvious reasons I wasn't immediately comfortable with her reading this. I didn't have a smooth way to tell her no without cluing her in that there was something I especially didn't want her to read. She got increasingly angry at me for hiding something from her until she had to leave for work.

I'm not sure how to handle this. It seems to have blown up bigger than it should have. Do I come clean and tell her about my feelings? Do I make up some other story? Do I tell her to piss off and mind her own business about my private conversations (very out of character for me considering I've had no problems sharing things with her prior to this case)? Advice appreciated.
