When I was 16-17, I was with a girl who I loved at the time. We talked a lot about getting married. I asked her if she wanted to marry me and she said yes and I gave her one of my mom's rings to put on her finger. I don't know if we wrote any vows but we said vows and promised to never leave each other. We had unprotected sex numerous times before and after as well and we declared ourselves married afterwards because sex consummates a marriage. We might've considered ourselves married for a week or so. I think I may have gotten her pregnant and she had a miscarriage but I'm not entirely sure about that. We had unprotected sex and didn't care if we had a baby because we wanted one. After all was said and done, we didn't genuinely consider ourselves married. We still considered ourselves boyfriend and girlfriend. We weren't legally married and we still lived at home. We were only together for about eight months to a year and we broke up numerous times. It was the most immature relationship I've ever been in. I'm 23 years old now and I've been with the woman I truly love and want to marry for six years now. I want to have a true Biblical and Godly marriage with her. I've convinced myself that I'm married to my ex girlfriend and that if I preceed forward in marrying my current girlfriend, it would be adultery. This is one of the hardest things I've ever struggled with in my life. I realize how young and immature we were but people in the Bible married at a much younger age and there was no such thing as a legal marriage back then. I can't tell if we were truly married or if I'm just condemning myself and overthinking. My ex girlfriend is engaged and I just want to move on and live my life and marry the woman who I'm with now. She's the only woman I want to settle down and have a family with.
