As for the co-habitation...let me give an example of a woman I worked with.
She has two grown daughters. The one was married twice...divorced twice....with a kid from each marriage....and has now added a third child out of wedlock. Both of her ex-husbands had found new woman and had kids, as well.
The other daughter lived with a man and bore him two sons, and has since broken up.....he's remarried, to another woman with a child. She has now hooked up with another man, who has three of his own kids.
I have to make a chart to keep track of the drama.
In the end.....everyone is miserable and unhappy. Seriously. The daughters haven't learned from past mistakes, and are still jumping in to bed with men whom refuse to commit to them, or their children....and are only producing more kids from these unions.
Each one is on some form of federal assistance, because they never finished school, and have no stable career. The men refuse to pay child support and are also either unemployed, or paid under the table.
The kids are one weekend here...the next there....middle of the week this grandma has them, but, she doesn't want the other brother because he's not her son's son....
Seriously. It's a mess.
....and when I mentioned to the woman I worked with (the grandmother of 5 of these children - born of 2 women, and 4 men) why her daughters don't either settle down, or just resign to live "alone".....she rolls her eyes at me....as if I don't understand the ways of life. This woman, herself, stole a married man, and was pregnant before married, then had three kids (her son somehow has managed to steer clear of all the drama, and hasn't fathered any children)...only to have another woman, steel her husband (whom she stole from another) from her.
At least, if they were married, there would be some "order" to this nonsense.
My heart breaks for all these mismatched kids.
However, as I've often been told....I don't know anything about it, as I'm not married, nor cohabitating, and therefore, have no real experience.
