Everyone is right about going slow. It may be unfortunate for you, but you need to go with things at her pace. Thats the only way she is going to be able to handle it. ALSO!.

This I feel is something very important. The way she feels at one point about something may change within days, or hours, or weeks. So when she does come to you to talk always let her know that you are open to thoughts, ideas, changes, and questions. When i came out to my SO there were things that she told me was okay and then changed her mind because logically it made sense, but emotionally she could not handle it. This is going to be a process.

Sheila is right about her possibly joining the FAB forum if she is ready or being able to talk to people, because its not so much that you ripped the doors off of the closet. You pulled her in and shut the door, because she now shares your secret.
