How do I help? Should I help or let him grieve?

My ex broke up with me recently. Soon after, his dad passed away from a tragic hit and run accident. His father was in really bad condition. As a refugee claimant he is unable to go bck him and he is stuck in the current country he's in. His case is completed so any suggestions wouldn't suffice. Although he broke up with me in the most painful way I feel like im obligated to support him through this time. He was happy I came to him during this hard time. But now he says he's ok without me. He doesn't need me around for now.

I have two questions I would like your insight on.

1. He's gone very quite about his father he doesn't talk about him. He acting normal and laughing and just being his normal self. But he's avoiding of people like his friends. I don't understand it. I mean I know he's grieving and he wants to be alone. Ijust want to understand the part where he'd acting normal and if there'd anything I can do or just let him be.

2. His mom is back home. Since he can't go his brother is going in 3 months. They have property and stuff that the dad took care of. Now the brother may have to handle it. My ex feels like there is no life here and if it's worth staying. I'm so scared ik he's my ex but if he leaves I'll be shattered but at the same time I know this is hard for him and I should be supporting him with every decision it isn't about me. He says he wants me in his life before his fathers death but he's not interested in me. It's all just a big mess.

I need some insights and what you would do or not do.
