Is he over exaggerating here?

I'm using fake names here for privacy purposes.

My boyfriend (Josh) and I had a fight last night and he did not come over to my place after he was done work. No we do not live together but the night before he said he was coming over after work. The reason for the fight!?

On my snapchat story I posted a picture of the cookies I was baking. Sorry I've since taken it down so I'm describing it. The caption was "BAKING FOR THE CUTEST LITTLE MAN EVER" and I tagged one of my good friends in it (Chris).

Chris has an 2 year old little boy (Chris JR). Roughly two or three weeks ago I discovered that he loves cookies and said i would make him some.

Josh saw that on my story and messaged me like oh i see you're baking for another guy, have a good one and just went off. I was like its for Chris JR just relax. He whatevered me.

He ignored me. Hasn't replied. Didn't come over. Nothing. I feel like this is so petty. I've made stuff for our friends and kids and people before. This isn't a friend he doesn't know. Thoughts??
