FRiend of mine who I called some very nasty things because they were critsisng every mistake I made and pushing self improvement on me

This was a few years back during covid. They had aspergers and were critisisng every little mistake I made, and always pushing self improvement on me. In the end I snapped and called them a failure and worthless, told them their girlfriend was going to leave them and called them useless. I regret doingb this  as I was very close to this person, but enough was enough. There isnt a day that goes by that I dont regret what I did. I even asked them to stop pushing self improvement on me, but they refused. This person was masking and trying to fit in, very insecure about themselves and pushed that insecurity on me. I even tried reconnecting with them, but they were the same as they were a few years back. Am I the Ahole?
