Bottling it all up will only make it worse Half the reason she is suspicious is because you are hiding something.
The only hope is to come clean and hope for the best. This often means "dropping the bomb" on her. This needs to be done as tactfully as possible - reassuring her and letting her know you love her & don't want to lose her.
Thinking past step 1 is hard because you don't know how well she will take it. She will need your support & maximum help with the family.
I had to see a psychiatrist & gender therapist when the dam collapsed one night. In short order I explained why I sought proffessional advice & invited her along without being pushy.
This released the genie from the bottle and we started discussions ( & tantrums).
I had to start HRT to get back on an even keel & mitigate the angst, unease & dissatisfaction of gender misalignment. I started dressing at home with the wife's sanction.
This allowed all of us to keep functioning .
Hope that is good food for thought, my thoughts are with you,
Kirsten
