idk what to do

i used to like this guys but i was scared of a relationship. we weren’t very close for a while but we’ve gotten extremely close again. he helps me through all of my family problems and makes me feel happy. i think i like him again and i’m ready for a relationship. but i think my friend likes him and they’re going to a movie tomorrow and i don’t know what to do. It really bothers me and i confronted her but she told me i shouldn’t like him because its not a good idea.
