Having been a WAW, I am usually at least somewhat sympathetic to them BUT....

Let me get this straight - she walked out on you AND the kids nearly a year ago, barely came by so much as once a week, never took her children to where she is living and now you are actually LETTING her come into YOUR house to cook and clean on a DAILY BASIS???

What the hell is wrong with you?

HAVE YOU NO PRIDE?

And WHO the HELL does SHE think she is just waltzing back into YOUR home confusing the hell out of you AND the children?

WHY are YOU letting her????

Go to the source for your answers.

YOU DESERVE THEM.

YOUR CHILDREN DESERVE THEM.

SHE owes YOU.

And get her the hell out of your house until she starts making good on that debt!

This is insane!
