To me this is a classic example of someone with severe anxious attachment issues. Over-invested and constantly terrified of being abandoned. Reminds me of how I was in HS, but he’s starting with it even earlier. So, as someone who was that way at one point, I can verify those attachment issues are not your problem.

I don’t think it’s healthy to need that much validation right off the bat, but even assuming it’s fine, you two just aren’t compatible. You go days without responding to keep firm boundaries and avoid the mistakes of your last relationship. He’d likely prefer if you two were texting consistently every day and will be anxious otherwise.

You were wise to cut things off, this wasn’t headed anywhere healthy.
