Being friends with an ex- advice!

Hey so I had ended things ( mostly mutually but a little more me than him- my last words with him were that I was done with us) with a guy I'd been dating long distance 2 months ago. I ended up being in the same city as him sooner than I thought and I felt like enough time had passed that we could be friends. So I reached out to him about a week ago letting him know I was in town and that he always has a friend in me but he left me on delivered- so basically he's ignoring me. Before I ended it, he told me he wanted me to do what was best for me so I'm not sure if he's mad? or still has feelings? Idk if I should reach out again or just let him come to me when he's ready? I really miss him as a friend, as part of my life and I don't want to lose him. I also think I'm ready to be friends but how do I know for sure? Thanks!
