You really did the right thing man. I can relate I came clean with my wife right before we got married as well. In my situation we were both young and I had sent her away from me for a time because I was going nowhere and thought I was just dragging her down. I wasn't really ready to hear that she too had something to tell me, so a little difference, but we had been together from High School and we were both loyal while we were close together, but I guess I did the whole "free them, if they come back" thing. To be honest she never thought of us as broken up, so she felt so guilty about it. I sent her off and in 3 months realized what I had and came up with the most brilliant idea in the history of man. I thought "instead of sending her off because I'm so bad, why don't I just act right an be the man she deserves?" LOL, to me at the time that was a MAJOR revelation, to most others simple common sense.
But just keep praying, and being patient and understanding of her feelings. This is a lot to handle for anyone, but you are doing the right thing brother, and it will end up making your relationship stronger if you both endure. I pray His peace and understanding fill you both and you can come together to bring Him glory together.
