<human>: Can you condense the text into three sentences or less?

We were together for 12 years and we divorced 3 years ago. Anyway, I moved on, remarried about 6 months ago to a wonderful man. Yesterday I received a call from my ex's mother and she said that he has been fighting cancer for a while now and she thinks I should go and see him. 

I went almost immediately. When I got there, we hugged for 5 minutes or so, not saying anything. He looked so skinny. I asked him why he didn't call me and he said that "he didn't want to bring me down.... like [he] always [does]". I remember in one of the last conversations that we had, that I told him that I was too good for him, that he just brings me down. We were in the middle of a divorce, emotions were running high, but I guess he must have taken it to heart. He was really upset and crying. He was also on something, I assume morphine. After that he just kept asking me to go "please go, please go." Eventually he called the nurse, who came and asked me to leave.

I feel horrible and I don't know what to do. I didn't speak to his doctor because I was only there for 10 minutes, if that. Later that night I called his room and after I said that it was me, he hung up. His mother said that "this might be it." I don't feel right, just leaving things the way they are, but that seems to be what he wants. He doesn't have any siblings, never really had friends and as far as I know, he's not dating anyone. So it's just his mom that's there. What should I do? Keep trying to see him or leave him alone?
