Texting SO

I get it, not everyone is a texter or caller, but my boyfriend is like that only with me, his mom (who he isn’t close to), and his brother (who he gets easily annoyed by). We’ve been together for 7 years and he’s constantly leaving me on seen on Snapchat, Fb messenger, through text messages, any time I call him he gets easily annoyed, etc. Yet when his friends or legit anyone else messages him he instantly replies back.

A few times is okay, but I feel like he’s always doing this to me. Here’s a screenshot of our convo, that was the first time I even asked him about the food and it had been about 30 minutes later so I was just curious to know when it’d be ready. But he seems to always flip out on me any time I text him or call him...we were doing fine earlier today so idk what changed...
