He's been building up unhealthy connectiosn for a while then... This is common... If his income is important to you then you may just want to use that as a threat... When he complains about the drug test then tell him if he takes your son anywhere near OW again you will be reporting his drug usage to all his clients as well... And then hang up...
Truth darts would do best to center around healthy environment for son :
Drugs, lies, and anti-socialites aren't the best things to be exposing a five year old to...
You're ability to father this child is suspect at the moment : drugs, lies, and abandonment isn't exactly something he's going to be proud to hear about when he gets old enough.
Sons want a father they can be proud of - not a source of shame.
Something like that... It's important to hang up after you've said your piece so your point resonates.
