relationship

I am dealing with infatuation pretty badly -having sleepless nights and awful days. She just said that she isnt serious with anyone and thinks of them as jerks who fall and obsess. I try to hold back cz i dont wanna see that **** happen btween us. But everytime she comes to talk i just cant stop myself and then shes gone and i'm left alone again. I wanna get iver this thing. Please help.
