My (27F) ex-bf (36M) keeps texting me from spoof numbers. What do I do?

We ended on rather shitty terms, which is not my style. He was very hurt and turned angry, spiteful and cruel. I ended up having to ask his mom for help to arrange a time and place for me to go there and pick up my things. (He lived/lives with her). Obviously after the exchange I blocked him everywhere.

Over the last 16 months, he has driven by my house, sent me weird cryptic emails at work from a spoof account, left me an admin-related voicemail, and reached out to my sister and brother-in-law. Nobody has answered him.

Now I’m getting text messages from various numbers that are saying weird things. Needless to say, I know it’s him. For instance “can we have dinner Saturday evening?”, “I miss you, [pet name]” a link to a TikTok video (when clicking on the link it says his profile sent it) and pictures he took of my dogs.

I’m so over this. What do I say or do to get this guy to leave me TF alone?
