Stef, as I said in your other thread, you would be better off forgetting this guy, unless he is leaving the religion. JWs do not believe in casual dating, just for laughs. To them it is strictly for marriage and the man is considered total boss, especially after the "I do's." Much of their converting is done very subtlely, so as to not scare a possible convert away.
If you consider yourself a Christian, your whole belief system will change and you will be "taught" that you were raised wrong. If you become a JW, you will be required to minimize contact with your "Christian" family, unless they too convert. If, after being one and married, which will be the goal of his dating you, and you decide to leave the religion, or even if he does, you will be required to shun him, or he you and so will any children you may have. Your life will be centered around study of Watchtower literature and all other literature will be discouraged, especially using the internet.
Sex will be regulated by the Watchtower too. Oral and such is forbidden, although a few do it anyway. You will be required to give "the marriage due" when he pleases. You will have to do as he says, otherwise, you will not be considered a good wife. Marriage is the sole reason for a JW dating and they are encouraged to date only within the religion. Casual sex is strictly forbidden and he faces expulsion and shunning of he goes along with any.
Your attraction will pass with this guy, but the lifetime of pain you will get if you stay involved will last forever.
