<human>: Can you provide a brief overview of the text?

I feely honestly confused. No one knows this but me, because I care deeply for my SO. I've never encountered this before, and I've been with him for two years; no problem. We used to hang out; around the town, on trails, etc. and he started bringing his friend a few times. I've met the man twice, and he's amazingly similar to my current SO... We all get along amazingly. Laughs, shared sense of humor. but...

Somehow I have an unwavering sensation of pure longing when I'm anywhere near him. Deep in the pit of my heart, I feel butterflies. I feel like I've fallen in love again, as if he's taken my blank canvas and went all Jackson Pollock with warm colours. Which is odd, because I thought I was in love with who I'm *actually* with... I think he doesn't feel the same way, because he's never been with a girl, and I'm *with his best friend.* but sometimes I'll catch him glancing at me after he told a joke, or eye contact lasting just a second longer than it normally does.

I'll never, ever tell a soul, because I care so much for my current SO. He's sweet and means the world to me, and I thought I was in love with him, but I can't find the reason why this man, his friend, makes my heart skip beats. I have no idea why. Is it pheromones? Is it "love at first sight" ? Hard to believe when I in fact *don't* believe in love at first sight. I'm overwhelmed with emotion, he triggers some primal need for love in me. And I just want to feel that way for my SO.

I feel like a bitch... How do I make these feelings go away?? I would never cheat, and just don't know what this is.
<bot>: fell in love with my SO's friend who I've met twice. Don't believe in love at first sight but what is this...? How do I make this go away?
