I was destroyed inside. I knew I had to confess. So I went to see her the next day and told her we had to tell the brothers. I called my favorite elder from her house and told him.
I guess I'm the only one who looks at your story and sees you as the villian. Well, perhaps that is too strong a word but i read your own words and frankly I feel no pity for any of the suffering you got because of how you went about things. I see 5 times in that passage you state "I" and only one time it was "we" and it was basically only to tell her what you were going to do.
You decided for her, when you felt ready. You didn't ask her or give her any warning. While you were still at the house you decided to make the call. You could have said "I feel real bad about my actions and I want to confess to the elders next week". You trapped her and threw her under the bus just because you felt like YOU needed a change. You didn't just walk away and say "i need to stop". You didn't tell her "i want to confess so I'll not involve you and the co-conspiritant will be nameless". You didn't even say "i will go home and call"...you did it right there in her house.
If you did that to me I would feel that you would deserve any pain the elders and congregation heaped upon you. You didn't feel like telling your brother the elder about it so you weren't ready to face him. Did you ever think she might not want to face the consequences also?
I'm glad you didn't marry her but to make her seem like some kind of evil person because she is probably really bitter about you getting her in trouble. You never know the effect of your actions on someone else.
Now I'll get off my high horse because I have no right to judge anyone. I just commented that I can see her point of view and how you really screwed her even if you didn't screw her.
