You don't look old enough to be his Mum!
Boys are terrible at relationships, even with their mothers. I'm super glad I have my daughter in law who is amazng at relationships and helps us all stay glued and bonded! It's not that our sons don't lvoe us, it's jsut they don't think about it.
Thank you @riverflows for the compliments.
You are very right, they are poor in expression but they are sensitive, when time comes they will cry out also.
I am glad you have such a beautiful connection with your daughter in law, it is so important to have a good chemistry specially in that relation. My Son's ex-gf, she was a gem but sadly things didn't work for them and I really miss her. Anyways it's their life to decide.
