I love my best friend
What do you love about your best friend?
She always tells me when I'm making an honest mistake.
It's okay and normal to love your best friend in a platonic way. However, you should not get into a relationship with a friend because if the relationship does not work out, you may lose the friendship.
I'm feeling lonely.
Loneliness can be abated with friendship, but if you want a significant other you should try dating apps.
