I am very distressed. Let my boyfriend talk with me. He didn't reply to this message. Should I call?

Sure, you can call. When you make a phone call, you can say politely, for example:

What are you doing? Are you busy?

If he answers a little impatiently or answers that something is wrong now.

You hang up politely.

If he answers that he is fine now, he is not busy.

At this time, you can say you want to chat.

Then observe his tone.
