Wedding planning dilemma!!!!

CoNsTaNcE
I have a really close friend who is like family to me who is transgendered and i wanted him/her to be ome of my bridesmaids my finance is not having it. Hes not a homophonic or anything he's respectful of how she chooses to live her life. But says an invitation is okay but she can not b apart of our wedding of course i guess i have to respect his wishes becuz its OUR wedding but i kno its going to break her heart n she probably won't even attend. What to do or how do i break the news??
