"Please help! My husband wants an abortion for our fifth child"

From a blog reader in dilemma:

I have a problem please help me. I am 39 years and I have 4kids already. I just found out that I am pregnant again and my husband wants me to abort it, he said he is done with kids. The fact is that I have never had an abortion before and am very scared, how can I kill a child, my own child . But he insisted , not until I found out that he has a baby with 2 kids. I confronted him and he apologized but still insisted I take mine off. Do you all think I should listen to him and abort ? Or I should just ignore him and keep my child ?
Really confused .
