I NEED YOUR HELP PEOPLE!

I am in a group text with my friends from the gym. one friend is my instructor, who is the sister of the firefighter. we are talking about our jobs and how mine is boring, she says " now that you and my bro are getting married, he can take you out on some call in P-town (our local ghetto where he is a fire-fighter).

I almost died! So they all began to joke about our wedding and I did say "J, your bro is absolutely adorable" she ten says "OMG OMG,it really is happening!"

So, did she get the feeling from my feeding him and our facebook exchanges, or did he say something? What do I say? What do I do? She seems to be approving of it, if we actually ever did date.

Is this a good thing? is there a next step?!

help!!!!!
