How long is too long in terms of giving a new partner space?

This is a new relationship, only few weeks now. He’s experienced some family loss in the month of November twice. I am worried about his grieving process possibly affecting the relationship but I also do care and hope his mental health is fine. He had to go out of town for a funeral that was today but he and I haven’t spoke since yesterday morning. I wished him a safe flight last jn our conversation and haven’t heard from him since. I want to give him space and time but honestly if I don’t hear from him by tom I might start internalizing the issue and I don’t want to be selfish by no means. I think he should’ve have at least said thank you I made it fine or something. When we talk again, I think I should express in a nice way
