I wear black piece of rubber called and O-ring. To me it signifies my commitment to God. I usally get asked about my ring and i tell people its a religious thing or I explain what it really means in terms of my commitment to God. Is there a way to explain this to women I'm interested in and still keep them interested in me or at least not make them shrug off to something more interesting to talk about.
It is wonderful that you are keenly interested in spiritual matters and that you desire to please god. Whether you wear a ring or not, by your conduct and spirituality it will come out in conversation. It is normal to want to have the interest of other girls and keep that interest. But if you are committed to God, then wouldn't you want someone who shares your same values as well? As you already know, it is much more than just believing in God. So if these girls are no longer interested, or maybe some are but are not compatible with your for the long haul, you really would only be setting yourself up for disappointment.
Maybe, before you even tell her you are interested in her, observe them from a distance and discern whether or not a real relationship can bloom. This conclusion starts from the point of knowing who you are and then if this person fits into a place where the both of you can flourish. If God is first in your life, then God should be first in the life of your potential girlfriend. If you find it is not, and you are still interested, well one of two things will happen, you will date and it will end sooner or later, or you will begin and compromise on your stand for what you believe in. The principle that Jehovah has stated in the bible will never be proved wrong... You will reap what you sow.. (Gal 6:7)
