Reaching out to a grieving friend

C

My friend lost her dad on Christmas. It was tragic and awful because he passed so suddenly. I was able to attend the funeral and haven’t talked to my friend since. She asked for some space to deal with this loss and i’ve been respecting that. Because it’s been a month and half, I want to check in on her because her and her family have been on my mind. Does anyone have any tips on the best way to do a check in? I wanted to refrain from saying “I hope you’re doing okay” because she’s still grieving.
