You need some grace op and your ds needs some spontaneous, indulgent fun.
Let me tell you about DH's family. They were v v religious and miserly and everything was eked out. Sweets were once a flood, christmas presents were one and worthy because christmas was about Jesus.
So, the dc remember a shared between ice-cream on chilly holidays in Brid and the cake for 4 being alwats stretched between 5.
At 18 they all went to uni. At 21 the girls had become v alternative and left for the antipodes. Both have rejected marriage and a conventional life. One has three uncontrollable teens and is alternatively dour and whingy; the other more happy go lucky but addicted to chocolate and good food and is v overweight. There is mega guilt from both about just having a laugh and bloody good time for the sake of it.
DH turned out alright although is in their eyes a capitalist bastard. He has type 2 diabetes and still secretly snaffles mars bars.
Did I mention when fil died there was over a million in the bank. No joy, no pleasure, no small indulgences. Just mean spirited fucking meanness. ILs bought DS's first birthday present in the ELC sale after Christmas - a tractor reduced from 25 to 13. They were so pleased with themselves. DS was born on Christmas Day!
So, 2 miserable dc who left asap and one diabetic choc addict who also never went back after he was 18.
Joy op, Joy. Does it not fill ypu with joy to watch your son's childish joy at childish things.
