Can I get any answers?

Me and my boyfriend just had bad fight all because I had post on social media ( Instagram) “ ask me a question “ he seen that I had post it and asks me about it & I had no answer for why I had upload it.. my intention wasn’t to piss him off I guess I was just bored and want to see what people would ask me, so once I didn’t answer him he Immediately told me that I was single. Started packing all this clothes moved his dresser by the dumpster.. took all the food he had bought & he left and went to his mothers house. Well he had actually ending up coming back the very next night asking for a key to the house to be let in. Was I necessarily wrong for doing what I had did ? Was he being bitter by taking the food he had bought as well to his mother place but still here?
