Marriage??!? 😰😐🤔

Kelly
Im 19 in the military and me and my boyfriend have been dating 5 months. I love my boyfriend so much. I know I want to marry him but when I come down to it and I really think about being married. I don't know if I'm ready. If I honestly truly am ready to spend my life with him and him only. I'm scared. I want to only marry once. I don't want to be that stereotype. We weren't planning on getting married till I was 21. But now we're thinking about doing a courthouse wedding. Then real wedding at 21. Help... Idk what to think anymore..
