No specific question, just need your thoughts

I have been in a relationship on and off with my bf for 3 years.

Because of the virus, we are now in different countries and in a long distance relationship with different time zones. We don't speak everyday, but when we do it's over 1 hour phone calls, in recent days he hasn't replied my text and not returning my calls, my last text I asked him if everything is OK? And he didn't reply..

I am going to stop chasing him now and see if he will reply. I feel there is nothing I can do but wait for him to reply now.

I am always the one keeping in touch, messaging him, calling him etc. I just feel sad that he can't even reply a message?!?!
