Similar happened to me with my ex. We had been broken up for 2 weeks and he started messaging me. Not daily, but often enough that it was making me even more emotional about the breakup. He would send me messages of songs to listen to, or say oh you're not replying I guess. (As if they assume we will)
My best advice for you. Is to make his name in your phone something funny (my ex for example is saved in my phone as, dumb little liar) and as soon as he sends me a text, I read it, reflect, and DELETE.
You broke up. He can't know how you are doing anymore. And quite frankly you should feel proud that he is so interested and that you're strong enough to not answer! You have the upper hand! I also got rid of social media, and every so often I post a photo or two. But keep focusing on you. If you have the urge to reply, text the response to a friend, or even write it in a note book, or notes on your phone. I think I have about 200 pages of notes of replies to texts I never sent!!
Keep not replying, and eventually you'll laugh when he tries to even wonder!
