You are correct that women must be responsible to themselves and know that should they choose to take the risks of carrying a pregnancy to term rather than having an abortion, they will likely be raising the child they bear without much help from a man. 

It's a good idea too for a woman to know that once pregnant and having made the decision to carry the pregnancy to term, she should avoid cohabitation with the biological father before the child is born should she wish to avoid involving him in the life of her child, frequently a smart move in many circumstances.  Understanding the ramifications and commitment required for child rearing will cause many, especially young women, to make the wise choice of delaying parenting and choosing abortion. In most developed countries women are well educated in their rights and make such decisions without major dilemmas. Waiting for the right time can help women to select better quality mates and potential co-parents for their children.
