Should be upset if a guy refuses to spend time with me before he leaves to go out of town.

I been seeing this guy for awhile.

We spend alot of time together. Every weekend. He is deciding to go on a 3 week vacation. I am going to see him nor will he see me. I asked if we can spend a night together before he left he makes it seem like he is In such a rush to leave that he refuses to spend time with me. I told him how I felt. He was cliche about the whole thing. I was upset with him. My only concern is should I be disappointed with him because he won't spend time with me.?
