He flirted with me and later I found out that he was engaged ?

I have known him for about 4 months. He is kind and flirty towards me. I started to like him and I heard some people talking about him. He is engaged but he doesn't want to marry her. He never told me about his relationship. I asked him about it and he said I am going to break up with her and I don't want to marry her. I only got engaged to her for my mother. Should I believe that?
