Can someone please explain this reaction?

Hello everyone.

Last night my bf and we’re a bit annoyed of each-other. To be quite honest I think he was pissed for whatever reason and I was being pushy about it. I think he was already having a bad day because he was acting very serious with me. I showed him a tik tok and he didn’t seem too pleased with the type of content I follow. Content is pretty much hip hop choreography, fitness Influencers. Some girl was lifting so heavy. I said “damn I aspire to be like her one day”

He told me I’m annoying and rather not text. Ok😕

I went about my day. Got Starbucks in the morning before heading to work and posted a cute Starbucks pic and captioned it “don’t know what I’m more obsessed with: gym or caffeine”

Keep in mind he had not texted me since the night prior at 9pm. It was already the next day 1pm. He texts me at 4:55 pm.

So iPhone users, as you know if the text is blue it’s iMessage which means you’re texting another iPhone user or that you’re both using data or wifi to send texts. If it goes green as “text message” then either that persons phone is off, you’re blocked or just don’t have wifi or data …

I guess my texts weren’t coming through. It came in as regular text message but my phone was NOT off and he was not blocked.
