So last week my boyfriend got invited to a family function a couple of hours away from home and i talked him into us going and he agreed. So I requested the day off because he told me too & we were gonna go in advance and I was able to get it off so fast forward to this week Monday and my boyfriend tells me I want to stay the night out there so I tell him I can't because I only requested the day of the function off because I had to work the next day. (Which we had agreed that we were gonna come back that night)So he threw a fit and told me if I can't stay the night then it's pointless of us to even go for the day. So Thursday of this week my aunt messages me asking me if me and my boyfriend could babysit her kids the same day of the function.( so I agreed because my boyfriend had told me we weren't going to go, so I assumed we had no plans) so then Friday (yesterday) came and he changed his mind and told me that we should go, but I had already agreed to babysit and I wasn't going to flake cause that's not the kinda person I am. & I had let him know that I agreed to stay back and babysit because he told me that we weren't gonna do anything after all. But anyways he tells me that his gonna go anyway and stay the night while I stay back. So honestly I get a little upset I tried my best not to show it because it's his family and I'm not gonna stop him but like really, you tell me to request the day off and I go out of my way to request it off for him to tell me no because I can't stay the night out there because I have work the next morning? And you leave me here. Idk if I'm over reacting but I feel like the right thing that he should've done was for him stay here with me because we were in the plans together.

But I would appreciate any input to know if I'm over reacting or not.

* I do want to add a little more I appreciate the responses and I agree I shouldn't be upset because it's his family, but that's not what makes me upset, it's his family I didn't stop him I even offered for him to take my car to drive over there. What makes me upset is the fact that I went out of my way to request the day off because he asked me too and then told me that we're not going cause I couldn't stay the night out there, and then last minute changes his mind again. I didn't mention either I haven't went to visit his family in a while because I'm a fulltime student and I work full time so it is not easy to find extra time and he tells me that I need to make time for his family, so when I finally have the chance to get the day off he does that. He doesn't know I'm upset, I was just thinking about bringing it up to his attention when he gets back that that isn't fair to me that l requested the day off for nothing pretty much and it's not okay that he tells me that I don't try and make time for them because when I attempted and I had the opportunity this happened.
