Kinda similar in my situation. I had a short relationship with someone I fell head over heels and he dumped me when I found out he'd been lying. Went NC for two months, got vulnerable, texted... He told me to wait a few days but I was hurting too much to wait and just said my piece in two days.. only to find out his family passed from an accident on the same day I broke my NC. I felt horrible, blamed myself for the bad timing (not to him), offered condolences. After a week I checked on him and he was doing better. I figured I won't be able to move on if I kept thinking about and checking on him, told him if he needs something, let me knomake. NC since then. This was a major setback for my healing though because I felt so bad for him emotionally. But being broken up, you are supposed to heal yourself. You already gave the best support of offering help as you said in the comments. If he needs you he'll reach out to you. But you SHOULD NOT be waiting for his reaching out to you because pining over this will put YOUR LIFE on hold. He decided not to keep you around during his emotional period. Respect the space he needs. Move on. If you keep on supporting him as an ex for how long ever and turns out that he is not coming back to you, you will be hurt. You did all that you could. If he's coming back, he will at his own will. Just live your life as you need to now. It will be okay to check on him once, but don't make it twice because that'll make it a habit and your emotion will start wandering back to him. Just take care of yourself! Our situations aren't exactly the same, especially since your breakup happened after his mom passed. Grieve your own breakup, feel your emotions, take care of your body and mind as your priority. I know you said you do not feel like moving on but you have no idea how long his recovery will take.. Without a guarantee that he will be back with you. If it happens, it will, but assume that it won't for your peace of mind and focus on yourself. You won't be able to move on that fast since your emotion can't be switched off as you said. Concentrate on getting used to being single and out of relationship for now.. That being said, I give my condolences to your ex's family and wish you some strength that I lacked during my vulnerable period..
