Accidentally outed among queer friends in minor way?

[Aazhie]

So this is relatively minor but wondering if anyone has advice all the same XD

My friend was visiting, my roommate is also FTM but more genderqueer than transman as far I as still know... My friend turned to me and said, "so excited you're getting surgery!" in front of him.  She and I had been discussing online before she drove through California to visit.  Never actually told my roommate, as the last guy we knew who got (sort of impulsively fast, but I might have done the same if I'd been in the same place!) top surgery became a huge subject of him getting upset and it became something I just didn't want to bring up as it got to be a bit much for me to handle his reaction.

I'm not wanting to bring it up myself with him, but if he brings it up, I guess some advice or general thoughts would be great? :C
