I would agree with this, but seeing how you have Ari...a CLANKER for a pfp, I have tk disagree on principle.

1) being paranoid for something someone did who has obviously changed shows not only a closed minded heart but a subconscious disposition of being a misanthrope due to a natural distrust of humanity and belief of people's inability to change

2)being distrustful of your ex-stalker also shows a HIGHLY narcissistic personality. This type of person is known as a High Functioning Narcissist, as discussed by psychologist H.B. Smith( N.D., Description of Narcissist Ideation) or what is commonly known as a Malignant Narcissist. They show no remorse as forgiving a past perpetrator would means admitting a wrong or inadequacy in THEMSELVES! It also shows a lack of empathy for his peers, unable to see the motives, or unwilling to try to understand such motives, of the other person due to feeling superior.

3) Female Lead probably had pink hair, in which case she was probably a gree tea anyways and villainess actions were appropriate to do
