What does this mean

Me and boyfriend had a really bad argument last night he was saying he was fed up of things and me nagging at him 24/7 and so I said “don’t tell me you planning up splitting from me” and he’s reply was “I’m going to bed” and I said answer me and he just kept saying “I’m going to bed” now I’m here crying!! Not knowing if he wants to split up because of course he hasn’t have me a proper answer so now I’m worrying like ALOT, I can’t sleep. What do I do? What do take as an answer? 😞😭
