I know way too many people who have no relationship (good or bad) with the person they had a child with. Getting a cheque from a government agency that disperses child support is not a relationship/tie.
Bullshit! Kids deserve two parents. And, let's be honest here, it is the father that is almost always seen not as a parent, but as a "cheque from a government agency".
If you are a responsible mother, then you will work with the father for the sake of your child. It is ridiculous that for all the talk about equality, fathers are still not considered equal parents.
Breaking up before you create a child together is a perfectly reasonable thing to do.
