Shitphobic

My girlfriend is shitphobic, i dont know what to do, pls help.

So my gf was taking a shit in the bathroom and the door was unlocked so i walked into the bathroom. My gf told me to get out but i really wanted to eat some shit. I told her i would leave if she gave me some of her shit but she started screaming at me to get out. I ignored her and grabbed some of her shit and she started to scream even louder and kicked me out of the bathroom. This has been very traumatizing for me.
