Hi HM,
Yes, there is a chance that he will respond to you.
The good news is that he saw your text, which means that he hasn’t blocked you.
This indicates that even after hanging up on you, he hasn’t been willing to completely sever his ties with you.
As long as you don’t try to contact him from here on out and thereby give him an opportunity to start missing you, there is a chance that he will consequently respond to your text.
