Honestly, the best thing you can do is ask him. If you're never sure on how deep you need to go in supporting him, ask him what h may need from you. That said, keep in mind he just lost someone, so his head is going to be all over the place. The fact you're asking him how you can help will mean something. It will matter to him that you want to be there to help him through his struggles even if he isn't truly sure what he wants right now.

If he asks for some space, give it to him, but don't be afraid to message him now and then just to make sure he's ok because after all, you are his girlfriend and you want to look after him.

We actually have an article on how to support a grieving friend which may be of use to you. You can find it here.

In terms of splitting with him, I recognise you're trying to think about what he may need, but realistically, he just lost somebody. Ask yourself, do you really want to make him lose another person? Do you feel this is something he could do with right now? You need to ask him about what he wants.

I understand you may want to be around him a lot and look after him, just remember that grief is something that can be incredibly difficult to process. Just take your time with him. Be there to help him and allow him to work through the pain of loss.
