Okay so tell me how y’all would feel. So backstory, I (23F) took my bf (27m) to a house warming party. My mom and I were playing with a kid (5 m), like timing him how fast he could run and come back, and my mom and I were HYPING this kid up right? As one does to a child. Saying “wow you’re so fast” shit like that. And my bf is sitting the next to us saying “you’re not even fast, you suck, ect” my mom and I were watching this kid get upset with his comments so we decided to switch the game. Now we found a tennis ball and the kid would close his eyes, we would go hide it, then he would find it. (We were trying to come up with stuff because he was the only kid and the house had no kid stuff.) So the kids having a grand ol time and then asks my boyfriend to hide it and hands him the ball. My bf then looks this kid dead in the eye and throws the ball into the woods… I was extremely uncomfortable with his behavior towards this kid because how tf am I supposed to see him as a future companion and want to have kids with this man. When I asked him about his actions later that night, he said he was just trying to teach him lessons, and toughen him up for the real world. Keep in mind, we don’t know this kid, they have no past relationship, this was his first interaction with him. So then last night I brought it up again and said I was uncomfortable with the way he treated him and it rubbed me the wrong way. I told him that there is a difference between teaching kids lessons, and bullying them without cause. Instead of having an adult conversation, he said “okay well if you are uncomfortable then I’m just going to leave” (he was supposed to spend the weekend with me) he packed up his stuff and left without another word. The whole night has passed and I still have not heard from him. Thoughts? I am so baffled. I was just trying to express my concern and have a conversation about what to do moving forward. There was no yelling or acting mad even, so I can’t understand him just leaving. This is our first ever conflict in the relationship and I’m worried if something this small makes him leave, what happens when REAL problems come up? Thanks in advanced. Is him bullying kids a red flag worth breaking up over? Any advice on how to approach this and stand my ground instead of just letting it pass?
