Should I block my ex?

My ex and I broke up a little over a year ago. He broke up with me. I ended up having to move a couple hours away because he wouldn’t leave me alone but didn’t want to get back together and I didn’t trust t myself not to give into him.
The last time I saw him (May) ended in a big blowout and he was so rude to me. I haven’t spoken to him since but I heard he got 2 BUIs within 3 months and ended up in rehab to avoid jail time. Sounds crazy I know lol. Thankfully he kept his lucrative job. But I think he has not been drinking since which is good.

Anyway, I’ve left him unblocked almost as a way to leave the door open for an apology. He’s texted me 15 plus times with no reply on my end asking if I’m Alive multiples times , asking if I still had an item he wanted, asking me to play tennis, telling me it’s his birthday, etc. I’m starting to think he won’t ever apologize. should I block him or just continue to ignore?
