That person doesn't seem to have any intention of breaking the current good friend relationship with you for the time being.

Currently, that person may be busy with work or studying, enjoying spending time with other friends, and their feelings may be focused on things other than you. It is important not to overly worry even if there are no replies to emails or no contact.

Let's be careful not to act in a way that puts unnecessary pressure on that person.
