One girl whom I know for a 3 month's, who is 15 sed that she loves me, and sed that she wants me to be her boyfriend. Im 17 and i don't love her, I sayd no, but she was so sad, and I wished to calm her, I couldn't do anything. I felt like if I sayd no, after some time it wold make her suffer even more. Now I feel guilty of her feelings. What to do?
