How do feel about this? I need your help.?

I had been going out with my ex as a friend, we just go for lunch during the week. Some time he seems like a nice person but other time is like he doesn't give **** about.

I was sick in the hospital that happened on Tuesday. I was diagnosed with bad pancreatic. They left me there for 3 days to run some test. I called him in the morning to ask him a favor and tell one of my friends know. My other friend called him also and he sounded that he didn't care and told him that he was putting some cement to fix his house. I never bothered to called him back. He didn't go to the hospital neither he hasn't called. I'm really mad at him. Today is Friday 2:30 p.m and he just called like nothing happened. Well, I didn't answer him. I wonder if you would feel the same way. Because when my friends are sick that's my first priority. I know he is calling me to take me to eat and now it's me who doesn't care. I can buy my own food. I will appreciate your help in advance WHAT''S YOUR OPINION?

Thank you guys, I love all. (Forgive my grammar I'm so mad that I think I lost my head.)
