This is just my opinion, but I don't think you should have apologized for not working more... She should apologize for putting a house ahead of her child's college education... I am assuming she was a stay-home mom... If so, perhaps she should have put in extra time with your child so he could have received a full-on scholarship... I am sure that sounds ridiculous, but so does her insistence that you should have worked more... Again, just my opinion...
