My ex-partner recently took our 2 children to a camping party for one night. It was the birthday of a friend of his girlfriends. Our children are 10 and 12. On returning home to me, my 12 year old told me that whilst on the trip, his girlfriend lost a packet and people were frantically searching for it. He said to his father 'dad, what is it, it is obviously drugs'. His father then told him it was ecstacy. My son was extremely upset. His father then said to my son that he could show him websites where it says it is a good thing to take ecstasy. He also smokes cannabis in front of the children.
Has anyone had any similar experiences? I have spoken to my ex and he was very flippant and did not seem to think this a serious matter. I am not sure if I should contact social services. Does anyone know how they would deal with this kind of incident? I would appreciate any thoughts and information. Thank you.
