Hang in there Jo, for your own sake not anyone else's. On a thread like this I am cautious about making judgements but demanding to see you take your medication sounds wrong even if elements of his lack of trust are justified and he ought to be aware it is wrong. I would maybe tolerate it for another day or to in order to demonstrate your own efforts at putting things right but insist it has to stop after that. Congratulations on your 45+ days sober, that is a huge achievement on your part and you deserve a supportive partner.
