Pregnant man a father of the election which

Today I met a very confusing thing, need your help! I fell in love with a man, but from practical considerations, he is a man who can not afford, but still have to borrow money to maintain my life, I feel insecure. But now problem is that I am now pregnant with his child, has two and a half, I really do not want do not want the child, first, the 29-year-old woman out to do bodily harm to children is relatively large; second , felt that a child is really innocent, children really do not dismay.

If I can do and if hemarried, he can not give what I have and children, only on my own, I do not know whether they could become so powerful.
　　Another problem is that now there is a love love my man want to marry me. He is a relatively more men with a sense of security. He now thought that my belly is his child, and I want to get married soon, he said he would be responsible for taking care of me and children. But the child is not his. I dare not explain, I think, and he will be against my marriage him, and if he married, so he is not selfish?
　　I am now very depressed, and very afraid of the future life! Sometimes feel they can not lie to him, or even want to tell him that this child was not his, as a man he will forgive me? Know the truth, he will accept me after and children?
　　I do not know how to do, but I really want this child, and the longer,the babygrowing, I do not know how, if the the child is and his father can not afford the Dad together or choose to love with my man? I was afraid of their choice will be wrong.
