Should I tell about my past to my husband?

Hello, I was in a relationship with a guy for around 2 years. He was a syco person. He wanted to marry me but his behavior was so stubborn and rude. He was ruling over me. Somehow, I decide to get rid of him. My parents were also against him. So i planned to get married as per my parents wish. I met a boy and our marriage got fixed. I am extremely happy with him. But i am feared that if he will come to know that i have a past relationship, he will make an issue because when we met for the first time he asked me for my past, I said no at that time because it was just a first meet and i was not prepared for this question. please help me what to do? I don't want to ruin our relationship for the sake of a useless man who didn't love me and made my life hell. I love my would be husband beyond limits and I will be loyal to him. Should I tell him everything? I feared that he will start thinking useless things which didn't happen (as all boys are same). My parents and well wishers told me not to say anything about this to him. What to do? please help.
