After a few weeks of not being able to get her to change her mind and take me back I looked on her computer and discovered the OM - that was violating her trust.
Wait a cotton pickin' minute...buddy.
You violated her trust??! Nuh, nope. It's the other way around. She violated YOUR trust by stepping out of your R and acquiring OM. To be clear, you have done nothing to violate her trust at all.
