I remember reading a story in which spike is rejected by rarity for another pony. This pony charms her to the point she trusts him but he takes advantage of her by spiking her food or drink or something and then deserts her. Rarity becomes pregnant and spike is left to clean the mess. I need to know the name of the story as im looking for some plot ideas and inspiration from it. Can anybody help me out ?

Broken diamond or polishing diamond

Are u sure the title u suggested is correct. Thanks for helping but it seems those stories with those titles dont involve much with spike as a character. I have suspicion that the story im looking for no longer exists. If somebody has an offline copy please share a cloud link or something otherwise provide a webpage link to the correct tilted fiction. I want u guys to confirm ur replies by speed reading.
