In love with my best friend

Megan

Yeah... so I don’t know what to do, or if I should do anything. I’ve always known that I liked him, I just didn’t want to believe it. But now, we are really close friends, and whenever we talk to each other, we stare at each other in the eyes and we don’t look anywhere else. I love it. But I feel like if I tell him how I feel, it would ruin our friendship. Please help
