You are right, but even if she don't have anyone to support her financially, I'm sure she have a home where she can stay. If so then she would have keep her children in the house before she go to the gamble center. Only unnecessary pressures makes people do the wrong things. Anyway, no body knows the reason why she did what she did or if she's even there to see someone, we don't know because it's all alleged.
If I can't tell you no, when there is a child or children involved, the parents must change their mentality and say that they are the only option, they are the ones who come first, the children must be option 1 because then why did they bring them into the world? That is how it should be thought and believe me there would not be so many child abandonments or anything similar, children deserve the best quality of life always.
