Promise rings and parent issues

Malinda

hi! So me and my boyfriend have been together for a good amount of time. And recently we have been facing problems with his parents. his dad is convinced I'm using him and manipulating him but I am not. I truly love this boy. I'm 18. he's 16. yes there is an age gap but we've been together for almost five years and I just turned 18. our relationship has never been about materialistic things or money. but love and caring for eachother. recently I have had a major brain injury from a fall and I'm in college away from my family so my bf has been trying his best to take care of me. this is why his parents have been so... Idk rude ig. they say I'm an adult and need to take care of myself when I can't even remeber where I am half the time. I'm surprised I'm writing this. I'm lost and hurt. on that subject but the real reason in writing is we just bought each other promise rings and are scared that if his parents find out they will take it. what's another way he can remember it's there without wearing it. if that makes sense. And any help on the parent issue is much needed too. so sorry for the rambling. my head is pretty messed up.
