Coming from the TBM side of things until very recently. My DH came out to me about 3 months ago. It's hard for both sides. I sobbed almost daily for 2 months (Pregnancy didn't help that). Only now have I begun my own journey to truth. Be patient. The things that have been hardest for me is feeling that my DH was keeping things from me and that things would continue to change to a different life than we had planned. It's terrifying. He went through his process on his own and left me entirely out of it. He's been going through this for a year now. Make sure you don't withhold your process but do not attack. My DH would say things like "You just don't understand what the LDS church is". Do not be dismissive of her current beliefs and feelings. Be patient and loving. It's especially hard because of the pain and anger you probably feel but if you're truly happier, make her see that. Be happier. There's so much disdain and anger toward the church out there that it's very likely she will be afraid you feel that toward her. Make sure to do your best to let her know you are not angry with her. Respect and loving, calm honesty is best. Good luck.
