Dear young lady, I am very sorry that Jack has finally turned out to be another fool. As a father of 3 in my 60s, I understand that your being betrayed again is so painful that you decide to end your hope of finding a loving soul mate. However, giving up hope could harm you in the long term, generating distrust in everyone, even protecting you from love. Well, now, how not to fall in love with a jerk ? I used to read a book about that, could it be useful to you too ? I wouldn't be surprised if a loving soul mate came along one day, sooner or later.
