Online dating is a way of long-distance dating, which exchanges feelings and interacts through the internet. Although you can communicate through text, voice and video, phone numbers and video chat are usually deeper and more intimate ways of communication.

If the man doesn't give you his phone number, video or voice, there may be many reasons. Here are some possible explanations:

1. He may not like phone and video chatting, or he doesn't feel personal enough. Some people prefer to communicate through text and voice rather than telephone and video.

He may have some privacy concerns, such as not wanting you to know his real identity or address. That's probably why he didn't want to give you his phone number.

He may have doubts about your true identity, or worry that you will reveal his personal information. In this case, he may want to keep a certain distance to protect his privacy and safety.

Whatever the reason, if you want to know him better, you can try to communicate in other ways, such as more text and voice chat. You can also ask him directly why he doesn't want to give you his phone number and video chat, and listen to his explanation and thoughts. The most important thing is to keep communication and trust, so that you can establish a healthier and more stable relationship.
