At what point is it okay to try to text again?

I know I’m not ready yet but I also have a lot of things they showed me that I just genuinely wanna ask about even outside of the possibility of a relationship, but I am worried about reaching out and sending myself back like a month to when I was in a dark spot post breakup. I feel significantly better now but I’m able to recognize that there are still lingering feelings and I just don’t wanna set myself back
