Advice on how to pull back?

I’ve been talking to this guy for a couple months and I realized we’ve been talking a little bit too much and too often. I’ve been trying to keep myself from becoming overly invested the whole time since our contact has all been virtual. I know he’ll definitely notice me pulling back and I don’t want to hurt him, but at the same time it needs to happen for my own sake. To start, would not responding to his texts for a day be too much? I don’t think I want to stop talking to him completely, I just think the contact needs to lessen.

Edit: I should also add that I don’t initiate contact with him like ever. I do sometimes send him things on Instagram or Twitter, but I don’t ever text or call first, it’s rare that I do.
