Thank you everyone for your replies! It has been interesting to hear the different reactions from your Ts. All the information I have found about my T is stuff that her husband had posted. His FB profile was not very private at all up until a couple of months ago. All the things I found out about my T are pretty minor and they're all good things. Like I found out she bought a kitten earlier this year which made me happy to know because I love cats.
But anyway, I'm not sure I'll ever tell her especially after hearing how some of your Ts got mad
