Hello *hugs*
you could have a look here for a few thoughts:
https://www.susans.org/forums/index.php/topic,184920.msg1644403.html#msg1644403Its for a ftm person, so a few things are the other way around... like clothing for women...
Well its up to you what you say since you know them best...
talking in a relaxed manner might help... remaining calm and stating facts and a few needs...
it might be a good idea to do this together with a therapist, its a process for both of you...
there might be a pair therapist, or she could see a therapist herself...
and there are resources for spouses of transgender people, support groups etc... i would just look for some helpful resources, some are not all positive...
well its a case of not fulfilled expectations, so you might talk about it... as said, imo best in a setting with a professional...
you might assure you of your love... and talk...
There are helplines if you want to talk to someone in person...
you could call here, people are there to help and give advice (there are many others):
glnh dot org/hotline/ (this is the national lgbt helpline)
translifeline dot org
And there might be support groups in your vicinity...
hugs
