Why my fiance reacted this way?

We are 38 years old and we got engaged last December. We were watching TV with his sister and an aunt at his home few days ago. I was sitting close to my fiance. He was changing channels and he started coment how beautiful eyes the girls have, how beautiful the other girl looks, every single time that a girl was show in TV. However I was there close to him and he didn't mentioned anything nice to me. I stared saying the same comments when handsome actors were presented in the TV. I fell mysell ridicoulous, making those comments. I was doing the same he was doing, just to show him how stupid this action could be. He did not react and he did not mention anything. However last night, we had a discussion . I told him in private the way I was felling when he make all those comments and he did not say anything nice to me. After that, he said that he was just testing me . He wanted to know if I was jeaulos and he don't like that. He said that we should break off our relationship.Plz help me
