Good luck with this--hope you click with the therapist and find that she is able to help you sort things out. Just for perspective, there are many "closeted" transgendered people like myself who do not "come out" to extended family, friends, or co-workers, but keep our gender expression private. Although this is by no means an easy solution, I want you to know that being transgender does not mean that you must transition or go public. I dress in private, wear some feminine clothing "stealth" every day in order to give some level of relief to my gender dysphoria, and have some other ways (like participating in forums like this, reading women's literature, etc.), of expressing what I believe to be my true gender.
Hopefully, you can find a balance between your femininity and maintaining your marriage and career. Glad you are seeking help and have started to talk openly with your wife.
