Just need some positivity

I'm 17 (I'll be 18 on the 20th of this month) and my fiancé is 20 (completely legal where we live). We've been planning on getting married on September 22 until my mom kicked him out (we decided to get married on my birthday). I just got back from basic training and am trying to juggle my senior year. The kids I go to school with and some religious personnel have congratulated me but for the most part people don't understand. I love him and am marrying him for that reason alone (in other words I'm not pregnant). I'm tired of my parents and their hatred for my fiancé (they hate him cause he won't become Mormon and bring me back to their church). 😭😭 Anyways I just needed to vent
