"She's been a heartache since you met her"?

"She's been a heartache since you met her". But the question is, to keep holding on ? Or to let go ? Is the pain worth the possibility of having her in your life ? Would you rather wait for her and do stupid things while you wait ? Would you rather move on even though you think she might be the one ? Can you stick around as a friend ? Or does it hurt when you're around each other ? Can you even imagine her with the boyfriend (That's specific to my case) ? Can you move on ? SHOULD you move on ? Does everything actually happen for a reason ? Or did we just randomly met ? Am I wrong when I think she's the one ? Or am I just a romantic fool ?
