I think that is true only when speaking of a girl who is not ready to be a mother. When a girl or young woman gets pregnant before she is financially stable, is married, etc, pregnancy is viewed as a bad thing. She should spend her youth developing herself and figuring out what she wants to do with her life and taking steps toward making those dreams become a reality. Children make doing these things very hard. Babies and young children require constant supervision and lots of resources both emotionally and financially. Babies require stability in thier lives and young parents are often not able to provide that stability. Babies are VERY expensive. If you cannot afford to properly care for a baby then having one can be considered a very bad thing. Once a woman is established in her life, has a career, a loving and stable partner, etc., then pregnancy is considered a good thing. In this situation children are considered good and that they enhance your life.. . After reading your additional information I would like to add the following. Not everyone likes and/or wants to have children. Your girlfriend seems to be one of these people. This is a major issue in any relationship. The fact that you two have such opposite opinions is a HUGE red flag. If I were you, I would seriously consider ending the relationship and finding someone you are more compatible with. I don't want to sound mean, and I'm sure you love her. However, why would you want to invest your emotional energy in someone who doesn't have a fundamental view in common with you. Good luck!
