1.   Woman gets pregnant by lover.  Does not like lover.  So she finds a nice boyfriend, sleeps with him (when she is 2 months along).  Tells him she is pregnant.  He is so happy he marries her, doesn't let her work, does all the nightly feedings etc.  When the child he thought was his is two years old she goes back to the child's father.  He threatens to sue for custody.  She then throws in his face that the baby is not his.  A paternity test confirms this.
