so i have over heard and my boyfriend never clears his search history off my phone so i kinda know what im getting for Christmas 💍💍 but im 18 and my parents dont want me to get married cause they think it would just be because of the baby but i really do love him he means everything to me i dont know how to function without him anymore hes a part of me ... and i would live to marry him hes my best friend so how do i go about it cause honestly i would say yes in a heartbeat but just explain i think we should have a long engagement??
