i'm scared for our future

so i (f) recently got into a talking stage with "isla" (nb) and we kinda have a "slow burn" type thing going on. i'm lowkey scared because they really do wanna decide if we should be friends or be in a relationship. i really like them and want a relationship with someone and also don't want to rush. last time i rushed, things went badly and ended in a few months.

i'm scared, though, they will decide i'm a better friend than a gf, though there are some good signs like them at least having feelings for me.

i know we'll still get to chat if they decide we should just be friends but i guess i'm just scared for whatever reason. i don't mean to be panicky, i guess i'd just like to have someone who's more than a friend.
