Annoyed

So my child father does absolutely nothing for her and has no interest of doing anything. He’s either doing drugs or drinking. Today I was looking on my old social media account seeing where he tagged me saying “Looookout babymama” and had my name in it about 3 weeks ago at 8 am. Not sure if I should say anything back or just simply ignore it and not give him the time of the day. He’s always been abusive towards me and done some other horrible things. Apart of me wanna ask what does he mean and then again I want to ignore it
