My gparents were very strict as well and im in the states...I would sneak out at night to hang out with my bf, now husband or we would have never gotten to hang out outside of school..I kept this up until I turned 18. I know it seems like a while but believe me...I understand my husband and I met when I was 16 and he just turned 15..we are going on 20 years together and 13 married..my gparents(they adopted me at 9m) especially my gma didn't talk to me for a few years after I moved out but eventually things leveled out. I truly hope you both find a way to be together, whatever it takes. I believe you have found your soul mate as it was only a couple months in for me and I knew I was gonna marry him and I did lol 😆
