I really really need some help and guidance in my religion and Interfaith relationship (this is long!)?

You can have all of the positive things that you mentioned through God and yourself whether it works out with your boyfriend or not. You both need to be honest and trust God to work it out if it is meant to be. You can't put your trust in any human being because we are all imperfect. We can help each other as he seems to have you; but in the end; we must each deal with our own relationship with God.
