I don't believe her. I think it's easier to say she doesn't love you because how could someone who loves you be such a jerk? And she's been a true jerk. She pulled that crap at home, having you escorted out for all the neighbors to see, to make you hate her. It's easier to be a jerk if you hate her. I don't believe her.
I think she wanted you to hate her because she got so wrapped up in her own life, her education and during that time, maybe you got wrapped up in other things too waiting for her to get that final degree. The difference is you didn't start something up with someone else. She did. I think if I cheated on my H, I would try to bail too. I would not want him to forgive me, I would be ashamed and want him to hate me and me to hate him. Easy way out.
