Abortion is not allowed in Islam at all unless to save the life of the mother. Those who help in abortion except for saving mother's life are committing a major sin and the money earned for Abortion is unlawful.

It is possible that he said what he said because of some misunderstanding and he did not really mean to leave Islam. In such case, he is still a Muslim. If you are sure that he has deliberately left believing in Islam and became a non Muslim, your marriage bond with him finishes as there is no marriage between Muslim woman and non Muslim man. When there is no marriage bond, there is no question nor need for divorce as marriage has already become nil and void. If a husband becomes a non Muslim, his Muslim wife must observe Iddah of Wafat which is four months and ten days. That is after being definitely sure that he has become a non Muslim.
