Is this a red flag?

[Bathbedandbeyond]

New boyfriend of around 6 months. He’s wonderful and we get on well. Mutual friends have a positive view about him and he generally has a great reputation.

Last night he went out with friends in a city around 40 miles away so he was staying over. He text me three times between 7-11pm, but I didn’t answer as I’d fallen asleep with the DC.

At 11.30 he called my phone and woke me up asking if I was ok. He sounded cross? I sent him a jokey text, which he didn’t reply to for an hour. When he did reply, he was normal, said he loves me etc.. but didn’t apologise for waking me up.

AIBU to think that last night was a red flag?

I don’t see it as a red flag at all.

He thought you were without children, and you didn’t respond to texts between 7 and 11 as you usually would.

He’s not going to think “oh maybe she’s knackered and has fallen asleep with the children” as he thinks they’re not with you.

He’s going to think “shit Bath would normally reply, I wonder why she hasn’t, I hope she’s ok because I care about her. I’ll call her now”.

That’s how I see it.

Definitely an amber+ flag, in view of those updates. He thought you were child-free and therefore assumed you must be out painting the town red when you didn't answer, hence sounding pissed off when you answered the phone to him. Also, I agree with @breakingthebank that meeting you after a night out is potentially quite controlling...

OR

He’s going to think “Bath doesn't have the kids I wonder what's she up to, I'll send her a text. She's not answering. What is she doing? I'll text again. Who is she with? Still no answer ,she must be up to no good.I’ll call her now”.

Either options yours or mine are possible. We can't know. Even OP can't know at this point in time. It all depends on what he says and how he acts once he sobers up. It could be worry it could be a controlling streak.
