Hello Jess,
It's just cruel to demand 3 months of RLE before starting on hormones, and I don't even think there can be a medical reason for it (like making irreversible changes before you may find out it's not what you want after all)
Probably it's a good idea to find another therapist.
From my own situation, I just started on hormones last week, and while I try to do as much as possible as a woman, the situation at home still prevents me from starting RLE. My therapist is fully aware of this, and one of the reasons I was allowed to start hormones anyway, was to make passing somewhat easier once RLE starts - which will be around the end of august.
Hope you find a solution to your situation,
Love,
Marleen
