Did I do the wrong thing?

guest
Tonight my sister was getting baptized. 
Tonight I also told the guy I'm dating that I would go to his sports game. I usually go every weekend, except for this past month I've only been going on Friday. 
The baptism was going long so I left before I saw her. 
I ended up going to his house to leave for the game. I changed and everything. But then I felt like I needed to see my sister. He was understanding and told me I could have just canclled but I was afraid he would be mad. 
I ended up changing again and going back to see my sister.
My thought process was that if this doesn't work out and I went with him I would regret missing it. And if it did work out I would know that he is understanding a good man. 
But for some reason I feel guilty for missing it. Like he'll be mad at me or something. Did I do the wrong thing?
