Can we get past this?

My ex and I broke up on March 9th but it didn’t really end there because he wanted to remain friends. A few weeks later he started giving me mixed signals so after that went on for about a week I told him I was unsure if I wanted to be friends. He got angry at first but started to break down. At the beginning, I was told no contact would be the best so that’s why I told him that.
Fast forward into 7 days of no contact, I was told that being friends (while adding a bit of flirting) would be the best to rebuild trust, prove that I’m able to make improvements to a possible new relationship (I was too emotional), and be the woman he fell in love with. I wanted to know if one of his family members (who’s in New York currently fighting the coronavirus) was okay and I wanted him to know that I was still there for him. He replied to me right away. The next day, I asked if he wanted to watch some technology videos (he LOVES technology) with me over the phone but I got no response. I’m really scared that I messed up by saying I was unsure if I wanted to be friends the first time. I feel like I hurt him by saying that. My questions are if you guys think I ruined my chances and if I can come back from this? I do still want to be his girlfriend but I fear he’ll continue to ignore me.
