Uh, excuse me, but the article refers to her ex-husband. Perhaps you should read it and we should ask where the hell he is?
Again, she is NOT a "single mother", she's a divorcee or divorced mother of three.
What's the problem with that term? Do we have to include un-wed mother's with the divorcee's and widows by coining the term "single mother", to ausuage their shame and guilt (the knocked-up un-wed mothers)?
