He hasn’t texted me in a week but is online regularly

About a month ago, this guy I’ve been talking to (LDR) for about a year and a half had a life altering experience. His role model, his grandfather, passed away. For a while he was taking care of him so i think it might’ve hit him harder. With everything going on in the world things just got worse and worse for him. One day, he said something extremely rude and unnecessary to me and although I’m there for him, I let him know it was uncalled for. He stopped texting me for a week but was online Instagram. I blocked him from there for my peace of mind, and from time to time (like once of twice) he would respond and say “I’m sorry I’m just going through a lot” and leave me on read again. Later I found out he was streaming on twitch again and he seems like he is doing better but he has still not messaged me, I message him regularly (maybe once a day) to just let him know I’m here for him and that if he needs anything I got his back, but still no response. I’m supposing he no longer wants me around. I don’t know anymore. Should i stick around and be supportive during this time like I said I would? Or leave for my own mental health? It drives me crazy.
