Hi all. After ending a 9 year relationship with my ex partner due to his cocaine addiction. I have found out the tests he would do to see our son he has been very sneakily using his friends urine. His friend told me out of concern due to my sons dad severe overdose symptoms as of recent. I’m not sure if contact should be allowed to continue at my songs grandparents (ex’s parents) which is where he’s spent time with our son for a few hours once a week since the split. When he’s not using or ill on a comedown he is a good interested capable father however I don’t think he will ever get clean long term & the lying of the urine tests makes me question if he should see our child at all?
