My AD who was physically and verbally abusive, texts me that he is sick/ in hospital

I have LC with him since a few years ago. I dont answer his calls/ grey rock his texts, most of the times ignoring his texts as well. These past few months, he sends texts that he is sick/ in hospital, he loves me blah blah. That is very likely true, as his health has been deteriorating since like 5 years ago. But every time he sends these texts, I have mixed feelings. My mental health goes up and down. Not only that, lately I am preparing for a medical procedure and trying to figure out even how to have this procedure because my AP has ignored it since I was a child and the issue made worse, that I feel my mental health deteriorating even further
