Anyone been in a LTR with a girl who is suffering heavily from grief?

My gfs mum passed away suddenly in her sleep with no prior conditions, about six months ago and is suffering heavily. She is seeking professional help after trying to deal with it on her own and with the support of friends/family/me.

In the last week or so she says she needs space and needs to be alone and to process things. I agreed and said take a long time as you need and havent spoken since.

Does anyone have any guidance or been through similar?

I plan to focus on myself in the time being, gym, reading, social circles etc. I'm not looking to start exploring other options.

Thanks
