My advice to you is that you have to let your parent know about what is going on between you and your father's sister, because you have hide the evil for longer, that is why it keep on growing in you.
Again that ur aunt, she is a devil's daughter @45, she don't think of settling down rather than uselessing your her & your's destiny shame on her.
But you still need total repentance & deliverance if atall that you neeed to stop it.
