I cybered this guy online i did'nt think anything would come out of it.?

but after a year of talkin with him he told me he was married..but by then i had fallen for him. already..it was too late i was in deep....and now 3yrs have gone by and.we've been cybering each other all this time , and i told him i loved him..crazy? i don't even know what he looks like, he always disappears and then reappears and i always submit to him everytime...he takes over my mind..is there song that best describes this madness?
