How to be friends again?

I came home after a 7 days relaxing in Greece with my mom. My husband was at another trip with some friends. When we met at home he spent 2 hours with me and went to sleep at 19:00. I was shoked by the fact that he didn`t wantet to spent more time with me when we didnt so each other for 7 days. We has never been apart from each other for soch a long time, and I misses him so much and now I am disepointed in him.
How can we be friends again? Am I completly wrong if I feel that he treeting me bad.
