<human>: A couple months ago, I started playing a DnD campaign with a new group of people. Some of them are my friends from a university club, but many of them are new friends. I've met the dungeon master (DM) before as he's come to a few of our club events, but I never interacted with him too much. Always thought he was kind of cute though. 

Turns out, he's an incredible DM - great knack for storytelling, supportive, has a Roman Mars-esque voice. He has a wonderful sense of humour and is a really sweet guy to boot. I'm rather smitten. 

However, I don't really know how to proceed. I'm not sure if I want to pursue it in case it makes the game awkward. I don't see how any scenario works out well:

1) I don't confess, remain hopelessly pining during game sessions, probably negatively affecting the quality of my decisions and the game.

2) I confess, he doesn't reciprocate, it's awkward, I lose the best DnD group I've had in years

3) I confess, he does reciprocate, I now need to navigate being the DM's girlfriend, which I am woefully unprepared for

Any advice would be appreciated. How should I proceed?

Can you give me a shortened version of the text?
<bot>: I have a crush on my DM and don't know how/whether to act on it because I'm afraid that anything I do/don't do will make things awkward for the group
