AIO for asking my bf where he went and what he was doing?

My (F22) boyfriend (M22) have been together for 2 years, and have been living together for 1 year.

We were cuddling around midnight when we accidentally fell asleep, and he woke up around 3am and decided to get up and finish the beer he was previously drinking, as well as turn off the lights. I woke up 5 minute later and got up to have a glass of water. We talked for 2 minutes and he told me he was finishing his drink and then going to bed.

I went back to bed and then 5 more minutes later, I heard him get up and thought he was checking on the cats because they were causing havoc in our laundry room. 2 minutes go by and I heard a weird banging noise (was probably the neighbours as we live in an apartment complex), so I called out his name a couple times and he didn’t answer. So, I texted him asking him where he was. 3 minutes later I called him twice and he didn’t pick up.

About 30 seconds after my second call, he texted me this. I’m a little unsure what I did wrong. It’s not like I was going to ask him anything else after the second question. I just found it weird he wasn’t answering and left without saying anything.

Anyways, please let me know if I went too far by asking these two questions because I honestly have no idea what the problem is.

And no, I didn’t assume he went out to cheat on me or something crazy. I strongly believe he would never do that. And he knows I’m not trying to accuse him of doing that either so I don’t understand the hesitation and arguing over answering a simple question.

Thanks
