I don’t know if I want to get married.

First time poster, short time reader. About in June of this year, me and my fiancé started dating. No more than 4 months later, we’re engaged. I should preface by saying we are both in our mid 30’s, neither one of us are virgins, but decided we would wait until our wedding night to have sex, and both raised in a baptist church. We are supposed to be married January first of next year, but I’m having serious doubts as to if I should or not. No more than a week after I proposed, I started getting a feeling that I don’t know if this is right or not. Then I start watching YouTube videos about destroying your Paul “arc”. About how being called to singleness is the most beautiful thing because of complete devotion to God. After I told her about my doubts of us getting married and how I wanted to be completely living in God’s will for my life, she handed me the ring and said when I figured it out, to let her know. I don’t know what to do, but hopefully I’ll get some advice as to what to do. I would talk to my pastor, but he quit 2 months ago and I don’t have any one to seek spiritual advice from.
