AITA for ignoring him???

My bf and I him (31) and me (27) got into a small petty dispute early last week about misunderstanding what the other person said and it that got a bit emotional on both ends due to our egos probably by saying who’s right or wrong…also should note this was our first “little fight”. We’ve been together for almost 3 months. So out of frustration, I basically knee jerked and said I think we should break up. This threw him for a loop and he got all upset and tried to calm the situation down by sort of changing the subject and asking if thats what I really want, or if I was just shutting down in the moment. We chatted a bit more but it got us no where and I told him that I’d talk to him the next day and hung up on him. Well 3 days passed and I never reached out and he eventually did via text by asking if we were still going to talk because of how things were left unofficial/hanging and how he believes everything is totally fixable with us but wanted to give me space to think for a few days and is willing to have a healthy face to face discussion. I didn’t answer his question and instead, got defensive by agreeing things are fixable but then saying how I was annoyed with him from our earlier discussion. He listened and again offered to want to communicate in person and resolve things like adults and said since he can’t read my mind or know what I expect from a partner unless I tell him. I ended up just ignoring his last message. He reached out again 2 days later saying this was his last reach out wanting to know if we were officially over or not, and that he’s still very much willing and wanting to talk to me, and apologized on his end and just wants to move forward with us. But if not, if I could just clarify closure directly that I’m not wanting to continue this with us, and how he’s not quick to throw in the towel when things get hard over small conflict. It’s been 3 days now and I never responded back to him. I think he got the hint. AITA for not being open to talking with him and/or properly communicating by saying yes with him by ghosting instead?? We still follow each other on instagram, and idk if he’s waiting for me to remove him or vice versa? It’s been 8 days since our dispute and almost 3 days since his last reach out.
