Disappointing Ending

I was surprised by the ending to Cloud 9. After reading As You Like It and  The Good Person of Szechwan that have endings where the audience is directly addressed with something reminiscent of a conclusion that gives the audience a happily ever after feeling, Clive's last line was a letdown  for me. He says, "You are not that sort of woman, Betty. I can't believe you are. I can't feel the same about you as I did. And Africa is to be communist I suppose. I used to be proud to be British. There was a high ideal. I came out onto the verandah and looked at the stars" (Churchill 87). This line perplexed me and I was not sure what he was getting at. I like that it ends with Clive speaking, as it began with him speaking, but I wanted him to tell me what to think or if they all did make it to Cloud 9 and could stay there.
