Over the years, my family has had less and less contact with my brother and his wife. We have absolutely no idea why, we have never argued, there are no skeletons in the cupboard, and we are a family who all get on well, its a complete mystery why. He has missed a number of significant family occaisons, eg weddings, significant birthdays, despite being invited. We always remember their birthdays and invite them at Christmas, and they send us cards, but that's it. My parents are now elderly and are in failing health. They are desperate to regain contact, but are scared of rejection, they just don't understand and feel so rejected.They lost a son in babyhood, and feel like they have lost a second son. I don't know wether to write to my brother to explain how everyone feels, to try and understand the lack of contact.
