Oh wow!!!!!! I don't envy you this position at all! You poor thing.

What would happen if you just said no to her living at your house? What would she have done if she hadn't met your son anyway? Sounds like an opportunist to me. That, and a baby machine.

I can understand your worry over this being your grandchild though. However, how did you become responsible for her situation? I fear that your life is going to become a nightmare and especially when she admits to getting pregnant by design. What is wrong with her anyway? It sounds like she was looking for a daddy for the other two and what better target than a young man who can't see the future of this nightmare?

If it were me (which it isn't) I would say no to this. I just couldn't do it. Maybe I'm selfish but I just couldn't--wouldn't do it.
