My boyfriend went to a family cruise trip for a week and didn’t miss me?

So my boyfriend of 6 months went to a family trip on a cruise for a week. He came back and I drove to see him cause I missed him so much. We had no contact during the whole week. I asked him if he missed me and he said “I was okay” that honestly hurt, cause I did miss him and I just naturally hoped he would have to. Is there a way I can communicate my feelings to him?
