Boyfriend yelled at my 2 year old

I am 22 and had my son at 2. My baby daddy passed away.... I have a boyfriend of 5 months. My boyfriend was over and I had a birthday party. At night I woke up to my boyfriend yelling NOOOOO! Somebody at my party left a fat shit in the toilet and my 2 year old is working on potty training. They didn't flush and my son saw it and thought "Ooooh chocolate!" My boyfriend is walking to the kitchen and sees my son inches away from taking a bite out of someone's turd and he grabs his arm and yells NOOOOO and shakes it until he drops it. My son is so hurt my boyfriend took his "Chocolate" away. I'm dying😂😂😂😂
