That poor little boy. Could you imagine being on the no-control end of that stick, listening to your mother say essentially that she didn't want him around? He's only 10 - even if she laid on the whole "this is your father's responsibility and he has to step up yadadada...," he probably felt so bad to be such a bother to her. Couldn't even nuke some water for soup?
F, please tell me you are on your way to finding a bigger place for all of you...sounds like the kids are going to need it!
