I agree, I think people often use things they have experienced as an excuse/justification for their behaviour.
That reminds me of that video she put up for Christmas showing all the gifts he had got her! The amount he must have spent was obscene. From memory she got an iPad, Dyson hairdryer, huge Jo Malone candle, loads of high end makeup and lots of other things that I can't recall... any one of those things on their own would be a main Christmas gift, with a few other smaller gifts. It was so OTT and she doesn't deserve a fraction of it. Why does he spoil her so? And does anyone know what she got him for Christmas?
