jvieve23 - I noticed that your request reads you and your "fiance." I think that deep in your heart you know why your desire has not been fulfilled. I don't mean to be harsh, but did you read the rules of this prayer site?
"Please do not ask for prayer if you are living in fornication (having any type of sex with someone) outside of marriage unless the prayer is to stop doing that now."
Being engaged and intending to be married is not the same thing as entering the holy union of marriage. You must repent of your sin, and continue in an abstinent, faithful relationship if you truly are seeking God's blessings upon your lives. My prayer for you both this day is that you would stop what you are doing now and seek to live according to God's Word and commands. Once you are married, and your will aligns with His, you will be amazed at the blessing He will bestow. May He bless and heal you.
