How are you as a man/woman first and are you stable ,not only as a christian first but as your own person .then you look at not only if you are attracted to the other but do you see who they are and not only do they say they serve God but actually do it in actions as well. That alone will tell you how they are going to treat you,not just on your dates but in everyday life because that alone should tell you how they will treat you in marriage.Because if you don't like how they are treating you in everyday life but you may be very attracted to what they look like. That alone should tell you if thay are right for you
