So my boyfriend's grandfather passed away 2 days ago. I'm trying to contact him n I'm texting him everyday asking how he's doing and to take care. He's not talking at all. He came online once and when I tried to talk he just read the message n went offline. He doesn't like talking about his problems. Everytime he has an issue he stops talking for like a day and when he is in a better mood he talks to me own his own. I'm genuinely worried about him. I don't know what to do. We can't physically meet each other rn and he's also not responding. What should I do?
