Wilf i hope its not rude to ask this......and ive only quoted your post because it rung a bell with me straight away,and from previous posts you sound like a pretty damn good parent to me !But a pal of mine recently went through the exact situation you mentioned......it took him near 2 years to even admit it to us and i could tell through knowing him years it absolutely broke his heart.......ive noticed small things over the months their relationship certainly seems different,ive spoke to him about it but he says its not.......but i can tell it is i think his pride is dented more than anything
