Don’t know what to do

So I’ve been dating this really nice guy for almost a year. It’s been pretty good but lately I’ve been a little disappointed because lately he keeps bailing on our plans. I have talked to him about this a couple of times and I told him I do understand he gets stressed out with his job but I still get disappointed when he calls saying he can’t make it cause he has too much work. This however feels like the last straw for me. Last week something happened to me that ended with me being rushed to the hospital. I texted him immediately and told him what was going on. He was super supportive…wanting to know everything that was going on. We had plans that night and he asked if I still wanted to meet. He wanted to make sure I was ok and I said I still wanted to since I thought that would help me feel better. Later that night he calls and tells me he has too much work to do and can’t make it. I know I should’ve told him that this really upset me at that moment, but I was just so mad and ended up not saying anything at all. At this point I just don’t know what to do. I really like him and really want this to work, but this really upset me. I guess this was more of a vent post lol any advice would be greatly appreciated
