He loves me to bits but he lied about being married!

Dear Diana,
We met in a train in September last year. He proposed friendship but I said no because he's very mischievious. In time, he sobered down. I said sorry, we became friends. I asked him if he was married; he said no. I told him never to lie to me. We'd talk long hours. He'd ask me about my family and tell me about his. He had helped me a lot financially and supported and loved me a lot and I found that I couldn't bear to live without him. I came to know that he is married and has a 11-month-old child. He always wants me to see happy as i have taken lot of trouble in life. I am an emotional girl so he saysu00a0 that he'd tell me when he felt I was strong enough to accept the truth.We had physical relation also but he never forced me. I told him that he should have told me the truth. He says he was afraid I'd leave him. He says he wanted a wife like me. He is going to divorce his wife because she doesn't care for him or his family. He says he'll marry me but that I'd have to take care of his child. That day, I consumed posion and he came over and made me throw it all up. Should I accept him with his kid or break it off. I am afraid my family and friends may disown me. Should I marry a married person?
