Why did he cancel plans with his best friend to hang out with me?

I have been dating this guys for like two or three weeks now and this weeks has been really rough as we were both extremely busy with work. He was on call at work this week and due to some storms, he got called in and worked a lot of long hours where as I am a nurse and work on a 12-hour shift basis, so I understand that we are busy and may not have a lot of time to meet and hang out. However now the only day we can actually meet is on Friday, tomorrow.

Today he told me that this weekend he was planning on spending the entire weekend with his best friend as elden rings is coming out on playstation and wanted to binge play it. This weekend has been planned from way before I came into the picture. Me being a gamer myself can understand his enthusiasm and told him that it fine and that he should go and have a blast with his friend and if he wants to, we can meet up next week.

He asked if we could meet for an hour today. I for one don't like the "I will try to squeeze you in schedule and so I refused saying I rather have a proper date than a speed date. I am also working a night shift tonight so it was not practical anyways. He then further tried to take tomorrow morning leave from work so we could have the date but he was not allowed so out of nowhere he cancelled one day with his best friend from their weekend to meet up with me.

He friend got pissed a bit but he said it's fine. My now concern is that I don't want his friend to think that I said something to him for not being able to meet all week and also I don't understand why he still went through all this trouble when we could have easily met next week since this week was not possible. Should I talk to him about this? I am extremely grateful that he went through all this hassle just to see me, do not get me wrong, I just don't understand why as I told him many times that he should enjoy this weekend with his best friend..
