Akash its not a good philosophy to reject a girl based on her past intimate relationships over and above when u love her. U need to change this crooked and completely irrational philosophy of yours. Even if the girl has a past that u dont like that does not make her a bad person or a whore.Or that does not prove u wont be happy with her in future. If u still insist on this u will always feel anxious and insecure even when u have girls around and when u dont have u will feel depressed. So change your view point and start thinking rationally about things. If u love her then Accept her with her past that would be best for u.
