Men and women have different attitudes towards sex. Men are naturally possessive and think that if they love her, they will get her. Women are very cautious about the first time, and the average girl will leave it to her husband, thinking that only in this way can she afford her lover. You took her by force and hurt her self-esteem. A woman who loves you again will leave you. Couples should respect each other. What you did damaged her image in her mind. Maybe she's insecure about you. You should apologize to her and take on the responsibility of being a man, unless you play from the beginning.
