Help.

My boyfriend and I had plans to hang out this weekend and hang out all day. Which he has had school so we haven't been able to see eachother as much as we used to. So tonight he made plans to go with his friend to practice bull riding. So he's saying he feels bad and he's selfish for wanting to go. And I told him that he can go but like he never told me about his plans with his friend and I don't know how to feel about it. I'm actually upset.
