Bf there for everyone else but me

So long story short my bf started at a new school in August. He made friends very quickly and was adjusting. Well last week his one friend got into a serious accident and was admitted to the icu. My bf stepped up and called her parents, drove her to the hospital and visits daily now etc. Which I was proud of him for doing since from my experience he isn’t the best at being there for people. Examples: I once went to the hospital after a concert with him and my mom took me and he went home to sleep, last year my grandfather passed away and truly I can’t ever remember my bf being there at all throughout the 2 months when I was constantly there even on the days he was brought back to the hospital from the nursing home in horrible conditions I have no recollection of him reaching out or even trying to be there with me. Well now I am upset since how he is acting to this person and her family after knowing them for 2 months compared to me who at the time of those previous events we were dating for 2-3 years is shocking to me. I overlooked this and assumed 1. Hospitals weren’t his thing 2. He wasn’t sure how to act/be there. Well from this event it is very clear that he can be there for total strangers (her parents) and he even took off work today to be with them. I truly don’t get how he can be there and emotionally supportive when he was never there for me. I can’t say anything now since I don’t want to sound mean but where was he when I needed him?? And why is it different now? Has anyone felt like this??
