Fiance Visa - K1/ K2/ K3/ K4

I have trying to get a visa from 2013, I have been to the embassy 4 times however it has come to my knowledge that I was on some type of filing... my mom was in the US to work she found love there but came back so her fiancé was filing for her via a fiancé visa which she put me Nd my sister on it because we were minors at the time. Her fiancé and her split and he stop the filing and sent her some papers in the mail that he had stop the process, so i’m wonder if it is a case where the paper is pending or dus result in me can’t obtain a visitor visa?? She even went to the embassy last week and she said they kept asking her about the fiancé visa which was ten (10) years again every has moved in with their life. My bf wants to do a fiancé visa for me will that have anything to do with me now??
