“Toxic love and limerence overlap in that the more "challenging" the potential partner seems to obtain, the more alluring that person may inevitably become to you. Love activates reward centers of the brain, creating a euphoric dopamine high that is extremely difficult to detox from, and in adversity-ridden relationships, dopamine tends to flow more readily in the brain when the rewards aren't as predictable such as in a toxic relationship. Psychologists have discovered that the brains of people in love resemble the brains of cocaine addicts especially in chaotic relationships. This is why you may experience a deep withdrawal effect when the object of your affection is not around or when they've withdrawn from you. Often we aren't obsessed with this person, but rather what they represent and mean to us.”
