Your friend needs to be taught a harsh lesson and if this is the way to go then so be it.
Keep all the stuff you have and sell it, instead of helping her, help yourself the money you get from selling bits and pieces will improve yours and your sons life.
It shudnt help some1 who clearly is screwing over the system, i know it will be hard but she dosent seem to care about anyone.
I know you said that you couldnt report her but if this is what it takes for her to pull her finger out then it may have to be done.
This will sound horrible but if they take her son of her and her new baby when they are born she wont have any money coming in at all. She is using her kids as cash cows.
