Hi mate, I hope you’re well.
It’s hard to give advice on specifically what you’re asking as of course there’s ways to get around it. A friend of mine got some to wee into a bottle and he kept it in his toilet hidden so he would pass tests when asked but ultimately for this this is besides the point.
If you are at the point of distrust where you are asking a partner to take tests and your partner is refusing to take them Infront of you then your relationship has become a game of cat and mouse.
For years I played the exact same game. Pleaded innocence and when disbelieved I played the victim. But when I was truly sober I was the one insisting let’s do a test come on I’ll show you.
Relationships of any kind are built on trust and addiction will strip a relationship of that trust. For an addict who is truthfully in recovery, after years of trying to convince people their lies are the truth the chance to prove without any doubt they are really sober by taking a test is something they would welcome.
I’m not saying he is using but I’m saying that as an addict in recovery, when I got sober I would take one at every chance to prove my sobriety.
I hope this helps
If you have any more questions let me know
Stay strong
