Don’t be sorry for the miserableness - that’s what this place is for.
I don’t mean to intrude but I need to say that I’m not sure your partner is the right person for you at this time in your life. I don’t think his attitude towards you is very helpful at all for your sobriety.
His distrust and the feelings it engenders in you are not helping your self worth at all and your instinct to take off the ring may be an indicator of how you need to proceed in order to restore your self esteem and aid your sobriety.
Best of luck to you.
