Advice needed on how to handle this situation please,long story. My DS1(13) whom I had when I was 20 to a ex-boyfriend & we split when DS was aged 1.Ex boyfriend has hardly seen DS through his own choice etc as DS has always gone to ex bf parents nearly every weekend so no excuse as he only lives 10 miles away he just couldnt be bothered. I have a very close relationship with ex bf parents & DS has always been close to grandad whom has been a father figure to him. But now ex bf has been diagnosed with cancer & is having chemo.And has now started asking after DS.So DS has now been getting pressure off grandparents to ring his dad. DS was very matter of fact last night when we where talking he said "Why should he be bothered about him, he hasnt bothered with me.What comes around goes around!" So how do we approach this subject to DS grandparents without upsetting them.
