Ok I am 21 and my boyfriend is 25. He has 3 kids from a previous marriage. I am not a virgin either and we have been dating for 2.5 years. So we do have sex regularly. He promised me he would ask me to marry him and have a wedding around Spring of 2011. After that promise he slept with my best friend in October. I broke up with him after finding out... but about a month later we got back together and I forgave him. He still says he wants to marry me, that he loves me, and what he did was really wrong. However... I have been wanting to get closer to Christ and I am a Christian but never really followed the rules of purity before marriage. I want to take a vow of purity until we get married. To be closer to Christ and to also make sure this relationship is not just based on sex. He seems to be very upset about this, as we regularly have sex 3-4 times a week. He now thinks im hiding something and he feels like it is out of the blue for me to do this sorta thing because I am kinda a nimfo. He just don't seem to understand that I want to confess my sins and take this vow, try to do right, and follow the rules and be closer to God. Because no matter what, in the end, God is the one who I will have to answer to. Yes, I realize this is going to be very tough, and him getting upset might make me say "screw the whole idea".... but its important to me. Usually he turns me down for sex, he has that power, always has. Now its like he don't know what to do, because that power is being taken away from him, and I am now turning HIM down. How do I help him understand?? What should I do?
