she has a lousy self esteem.
get to a accredited counsellor ...fast.
stop trying to please her. you wont. Everything you do will give her a furthher excuse to put the hump on.
dont involve family.
Counsellor again.
Is she a JW and what age is she. These are very relevant.
what level of education did she attain? I mention this as if she a returns to 'school' she will find a lot of other moms in the same mould of thinking.
she is not alone. There is a danger here that she will come under the influence of serial relationship wreckers. But counselling first and now.!!
dont try to do this on your own!
