I have to travel across the country today for work but all I can think about is how my soon to be ex is probably cheating on me

I have a critical meeting in San Francisco today but I’m supposed to fly out today and all I can think about is if she’s fucking me over while I’m out of town. I feel like I’m going to throw up once I leave. I’m sure she’s fucking some dude today. She’s such a slut. I don’t know what to do.
