Not sure if I should reach out to him today or not

So my SO has stayed at my place probably 90% or the evenings over the last several months. He stayed at his apartment last night and had a business dinner after getting off late so it worked out best. Which was fine. I’m settling the boys back in school and routine.

But he sent me a text after he got home and after we talked on the phone.

It was around 11pm(I wake at 530M) and he said I asked him if he was cheating on me few evenings ago. Well we were both drinking that evening and maybe I did just ask but I didn’t accuse. So what. I like to be open. Well he then texted how dumb it was to say. I apologized and I texted him back saying what time it was. And sorry I’m dumb. Then he texted me goodnight overly sensitive person.

It all sounds so immature as I type this but it’s real and I’m struggling. We’re both grown adults but I can make sense of this.

If I reach out to him today, am I in the wrong?

Is this a red flag?

Never gone this long without hearing from him. But just giving him space and myself time to think or maybe not think. Can’t make sense of it.

Thanks for reading
