<human>: Can you condense the text into a few key points?

And it's getting on my nerves. Me (19) f him (19) m. Been dating for 5 years.

 We go to different Universities, and live about a 20 minute bus ride away from each other. Whenever he makes plans with me he'll say.."Tuesdays good, lets hang out then. I have class early but that's okay I don't care." And then when Tuesday actually rolls around he'll be like.."Wanna just hang out ____ day instead? I have class too early tomorrow." This is really bothering me. Why is it okay one day but not the next, why even bother making plans with me if you're just going to cancel last minute. It's like he doesn't think things through. And if I get irritated by it he gets mad at me and says's i'm freaking out over nothing because we're still going to see each other at some point that week. I'm not pissed that he is doing the responsible thing and putting school first, i'm just annoyed that he makes these plans one day with me and then changes his mind on the day we're supposed to hang out.
<bot>: boyfriend makes plans with me and then decides on the day we're supposed to hang out that he can't anymore..a lot.
