Is this rude/blunt of me?

I had a tough breakup with my ex. He left me and jumped into a relationship within weeks. While we were together it was very toxic and also abusive on his part. I was name called, belittled, hit, mocked and bullied for years. Anyway we have a child together, I've made a post before how he asks how I'm doing everytime he drops our child home after having them at his house on weekends. He stays for about an hour after bringing our child home just to chat, he also txts sometimes which has nothing to do regarding our child. A few ladies on here told me to keep is short and don't entertain his questions and txts unless it's to do with our child so that's what I've done. He has just txt asking how our child is doing today and I replied saying "good". He immediately replied saying that I was being blunt. I don't know if I was being blunt but I believe I don't got to go into full blown convo, our child has been good today so I simply told him "good"! He's always known that I always played to his tune and I always tried making him happy even after we split. So now sees me coming across as blunt or rude because of the one word answer. It's funny how he can notice me being blunt, but couldn't notice me being hurt all the times he abused me and then left me for someone else! And now because I haven't replied to him because I've been writing this post (lol) he's texting me asking what's wrong!

Thank you ladies 🤗

IN RESPONSE TO ASH-LEE

wow! You have not read any of my previous posts clearly (or this one properly), if you had then you'd know that up until now I let that man into my home uninvited and unannounced since day 1 of our break up, I have also told him to only pay me half of the child support he is supposed to pay, because he has more bills than me and I wanted to try and make it easier for him, even though that fucker abused me! The one time I reply a one word answer and your saying I could give him more! He puts me down any chance he can get even now after we've split.. But you'd know this if you read any of my posts. The reason I gave him a one word answer (not that I should explain myself), was because I was falling back into his little games where the more he knew about my life, he more he felt he controlled me. He asked how out child was doing that day and I said "good"! What should I have said then? And I don't know why you said I was 'continuing' to be an ass when I was never an ass to begin with??
