Long distance relationship, does it last?

I've been in a relationship with my boyfriend living in the same country for 4 years, and now we're doing long distance and it's way worse than we both expected, we sometimes have moments of distance, barely any communication , and so much tension. It's sad because we were so in love and I know that if we see each other again it's going to be like before but due to our busy schedules we've only seen each other once this year. And he is going through a lot of difficult. Changes and I'm trying my best to be there but it's hard when it's through a screen. Will we get through this? Is there anyone with a similar situation?
