Give them space. Not wanting to spend lots of time with other people or feeling guilty at not acknowledging messages could be an additional burden for a grieving person, so it can be worth letting them know they can respond whenever they feel able, or simply send them a message to let them know you are thinking of them and that no response is needed. Adapting to life after a loss can take a long time and people should be allowed the space to process their emotions for as long as they need.
