Sold to the Circus

AITA: Am I the asshole?
Five years ago when she left, she broke my heart. No warning. No hey, this isn’t working out. No nothing. Just poof. One day she’s there, in my bed, and we’re talking about our futures. The next, she’s gone.
So when she shows up five years later and acts like she didn’t leave me with a broken heart, I get angry. So. Freakin’. Angry.
Of course, this is where I spiral. When we went through medical school together, we were on equal footing. Not anymore. Now I’m her attending, and I’ve made it my personal mission to make her life hell.
She wants to finish up her residency and finally become a doctor? Well, she’ll have to go through every single bad thing I can throw at her, first.
Seeping, maggot-infested, pus-filled bed sore? Yep, that’s hers to take care of. Man shitting every three seconds uncontrollably? That’s also hers. Man and woman having a baby while also in the throes of a divorce? You guessed it. Hers.
If I can make her leave after what she put me through, I’ll feel accomplished.
Only problem is, I forgot how determined Valhalla Singh was. Guess she’ll be reminding me.
Because Valhalla wasn’t named that for nothing.
