what makes you feel safe? what gives you peace of mind? everytime he goes to the area in the house where your meds are do you worry about if he is "looking"?
This is what was happening with me - so I put it thru some Al-Anon steps - I am powerless over HIS actions - I can ask my HP for the Serenity to accept that, but I can also ask for the courage to change the things I can- so what can I change about this?
I can put the meds where they are unavailable to anyone other than me. However I choose to do that. I refuse to defend my actions - I tell the A's in my life - "it's not about you - it's about what makes ME feel more serene."
It has taken me some work and support from my recovery friends to be able to do this - but it does help ME feel calmer and more at peace - hope you are able to find what works for you in your situation.
Wishing You Serenity & Joy,
Rita
