I will say this:
if you are actually planning on staying with this irresponsible harlot, then get a paternity test. If it's negative, you know she's a liar, and do you want to spend your life raising the smelly, disgusting bratty children of a whorish liar?
If you are doubting anything I have said, then you are indeed a fool. But that's ok, you make the lives of smart people easier with your manual labor abilities.
