God will help you through it and in the future if you date only Christians you will find the one right for you in God's will.You can continue to pray for your friend and you should be honest with him and tell him why and that you were wrong. The Bible says a lot of things that aren't relevant in todays society(slavery, stoning children, etc.). God loves all of his children equally and would never want to come between love.
I can be myself around him and I can praise God in all the ways I want and he supports me and joins in with all his heart because he believes the same and thinks the same.
What I´m trying to say is never settle for less than you are.
A Christian that marries a non-Believer starts from trouble.. If you go against this advice and others here, ask for prayer as you will need much.
Im agnostic and im also having this problem, because im not saved we both cannot get married even though we love each other so i did research myself.
Soo many people take the bible too literally and i dont believe it was meant that way. there are some parts of the bible that says women are not allowed to speak in the church.
