I think that your ex was searching for excuses to not be committed to you. Men who do not want to be with one person act like that. Do not think that it is your “fault.” If a guy is really into you he will be with you regardless you text him back in 1 minute or 1 hour. You wanted him to chase as most women do. In my opinion even if you texted him immediately, told him you loved him he would have made some other excuse.

Yeah, I’m sorry but it just doesn’t sound like he really wanted to be with you.

I think withdrawing to try to make him miss you is maybe not the best way to act. If something like that happens to you again, just open up to him: “Hey, it feels like you’re not getting in touch at all. I’d like to hear from you more often. Do you think we could talk at least once a day or something like that?” There’s no rules on how often people have to get in touch. But if you feel like he’s withdrawing, it’s worth having a conversation about that.

But again, probably not with this boy. Work on letting him go, and don’t blame yourself. Just go find someone who does really want to be with you.
