I think that you pretty much have your answer here. She gave it a try, and knew that her feelings were not the same after your betrayal, so she left. Its over. Take it as a lesson learned: Respect you partner, and your relationship next time.

Like you have hurt her before? Come on, what kind of healthy relationship is about taking turns hurting your partner? You need to make a choice and stick to it, and stop worrying about what if she farts to the left, or right.

You both need healing, and time and space to get your confused heads out of the clouds.

What ifs, are not facts in which to act on, let alone dwell on. Deal with the facts, not the fantasy.

Thank you I will
