It's been 5 months apart

You guys. My husband and I abroad but we're actually from Canada. I've just had my baby without him due to the virus two months ago. He couldn't come because they canceled all flights. I had to do it alone. He was really present during the first two weeks after his birth on video call ALL THE TIME. but after that he's just been so MIA. He's working from home.. he's always on his phone and says his battery is dying. We've been apart for 5 months now since I had to come here earlier so I would be allowed to travel. I tried to talk to him about it and he just got mad. I told him I'm starting to feel sooo lonely and dealing with all these emotions alone. He says he's trying. HES NOT. idk what to do 😭 how busy can someone be?
