Ex is still threatening me from random numbers..

I've reported him for all of his abuse and he has a warrant. He's obviously well aware I reported him. I blocked him on everything but I received these texts from a random number two days ago and I'm terrified.. He is making me want to reconsider reporting him because I am in so much fear. Can I just have some advice on what you all would do? Or what I should do? Yes I did report these texts as well. I know if I withdrawal the charges I'm just allowing him to abuse others and he deserves all the bad things but I don't want to live in fear for the rest of my life. What do I do? I'm assuming he's just trying to instill fear in me but considering I know what he's capable of, I'm just nervous..
