aww mon.. i don't know what to say
i hope he helps you out, you and the kids can't live on 200 a fortnight. Is there anyway possible you could get a partime job? like tupperware, or learning ladder? something that you could chose your own hours etc. learning ladder would be good, cause people wouldn't care if you took the kids with you... just a thought.

thinking of you, hope it works out. and i hope he realises that his kids are the most important thing xx
