How to not scare my ex off again?

Hey so I’m posting again haha. I have recently been talking to my ex again and we have had a few short conversations and he snapped me once. He has been pretty positive in talking to me even though he keeps the conversations short. However, I texted him again yesterday and he did not respond. I am not sure how to take this because during our relationship he was never big on texting and would sometimes not respond to texts or would respond after a day.

This was a challenge during the relationship because sometimes I would call him out on it and say that I felt he wasn’t interested in talking to me. I think he felt this was clingy behavior and would tell me that he just didn’t like texting and just because his texts were dry or infrequent that didn’t mean he wasn’t interested. So thats why I am not sure how I should take him not responding. It could just be that he didn’t feel like responding to that text but he is still open to communication. But I don’t want to constantly be the one to initiate things because then I feel like I’m being creepy. So does anyone have advice? Should I wait a week to text again? Should I not worry about this or should I take it as a sign he’s not interested and slow down?

Basically I am at the point where I am trying to rebuild rapport without being creepy and clingy. If anyone has some advice on how to proceed in general I would super appreciate it!
