Dont know how to help her

Not sure what to say when she says, "I cant do this." "I have nothing to come home to now that he is gone." "I dont want to get out now that I have nothing."  I know what she is saying and it doesn't hurt me.  I would think it would cause she has a family to come home to but I understand what she is thinking.  I thought the same for her.  When she gets out her fiance is gone (dead) her home is gone.  All she has is a husband she is separated from, a family she has stole from, lied to and treated very badly, and a dog.  But we do love her and she can live with us.  Not sure how I will handle that either.  I keep my bedroom doors locked when she is here.  I just hope and pray that she gets through this and I can trust her to live here.  Prison is sad but then to loss you fiance to an overdose.  I just dont know what to say to her.  I just keep telling her, "I know, I know"  I dont really know but I try to image what she is going through.  I am trying to help the best I can by telling her friends, being there for his family.  I will take pics at the funeral and be there in her place.  Oh this isnt fun!!
