Included in which group? You have made an accusation. Surely you have some basis for it, unless you are grasping for straws.
Are you saying that you chose to be a single mother? Is that what you will tell your child when she asks for her Daddy?
I don't think you did, but you did choose to shack up and play house instead of marry. Would you recommend that your daughter do the same when she gets older?
In many states couples receive the benefits of marriage (custody rights, common law, etc) without being marriage. It is this type of situation that I think discourages marriage and leads to bad situations for kids.
Like I said before, I think superdave, nathan and enderje got it right when they say marriage should be harder to achieve.
