If I were you. I will not call back. Because if you know your girlfriend, she would regret as much as knowing her lover came in contact with another woman than her.
If I were you I will never get back here again. If your girlfriend know you're upset. Knowing that her lover came in contact with a woman other than her.
If I were you, I would not get back here again. Because if the girlfriend you know you'll be very sad. Knowing that her lover come in contact with other girls, not her.
