Purity ring advice/help?

i like the one with just symbols better, and i think purity rings are kinda cool, i've thought about getting one but im just not sure i can make that commitment to not have pre-marital , i know it would be best to wait, not just 'cause of my religion (catholic) but 'cause with couples who only have after marriage they are 20% more likely NOT to get divorced in the future --- yet still, i can't c myself wearing a purity ring because i mean, what if i went back on my word? Then everybody would know i'd had because i wouldn't be wearing my ring anymore, that's really the only downside to wearing a purity ring i would think. So i commend you for being absolutely sure with your decision not to have pre-marital .
