I think you’re being a bit paranoid. It’s only been three days of not talking, and you’re already thinking negatively even though he already told you he’s just busy. From what you said, he seems like a good person, and even his friends say he’s decent and respectful.
Because of the message you sent him saying you want to end things, he might not reach out anymore because he could think you’re no longer interested in him. And since he’s shy, he may be even more hesitant to contact you again.
Try to wait until New Year’s Eve is over before you text her again, or just casually check in on her from time to time so she knows you’re still interested in talking to her.
I think she is also somewhat interested in you since she clearly enjoyed your first date. Next time you see each other, try to make the date a bit more romantic. If you really like her, show her clearly what your intentions are with her.
Just keep trying because that’s where you’ll learn from your experiences.
As for talking to him every day, it’s not really a good idea if it starts to feel like you’re too eager or chasing him all the time. Try to hold back a little and don’t be too available all the time.
For me, if you both have boundaries that you’re following, you should gradually level them up step by step so it doesn’t feel repetitive or like you’re getting bored of it over time.
