 flip the script. Like how would you feel if your partner was blaming you, accusing you, making you out to be someone who you're not because of someone that you probably don't know that's from their past? You have to realize that there's no correlation there. Not all men are the same, not all women are the same. And just because you had this experience in the past doesn't mean you're going to have that experience now. Point blank, it's not fair to that person and you shouldn't be blaming them and questioning them and accusing something because of something that your past partner did.
