Chastity and orgasm denial discussion

So this morning during breakfast I decided to talk to my wife about chastity again, it had been over a year since it had last been discussed. The last conversation didn’t go bad per say, but I was nervous and didn’t really explain well what it is or why it would be mutually beneficial. The conversation was going well, much better than last time…until I told her that it would stop me from masturbating and force me to positively channel that wasted sexual energy towards her and other positive things. Apparently my wife was under the impression that since we got married that I had stopped masturbating, I thought she knew but that it was just something that was never discussed. The conversation then turned to her thinking she is not good enough for me (not true, she is actually way out of my league), then she thought I was unhappy with our relationship (not true), that I would leave her(we are married!)…tears started pouring and it turned into a NIGHTMARE! I tried explaining to her that it is just an urge or a bad habit, it’s hard to control, has nothing to do with our relationship and most importantly that I always feel bad about it and I am offering a solution to stop for good. But by that point we were 1000 miles away from talking about getting a chastity device. Can anyone here offer any advice? Maybe a female perspective that might make sense to my wife?
