Toxic people know that they are ugly on the inside and know that nobody would be attracted to who they really are. They are not going to advertise their mental instabilities or their twisted emotional needs. A narcissist will not explain to you that they need to put others down because of their ‘babydick syndrome’. A sociopath will not explain to you that they need to hurt others to feel in control. Toxic people need to pretend to be somebody that they’re not to lure others into a relationship with them.
So, the question you should ask yourself is this: are you attracted to their false self or their true self?
