Re:
Thanks for the feedback. The 35 year old Oneitis actually sent me a text message on our last contact along those lines as well: "In retrospect, you are right. I did not feel the same way that you did. You deserve to be with someone who does. Please don't contact me again."
Looking back, I'm actually shocked at what ever drew me to her in the first place, as I now find her very unattractive both physically and in conduct, and strongly believe that I deserve better. But back then, I was so upset with how she treated me and I unleashed my anger at her. I replied that I hope she meets someone who will treat her the same way and even worse and that she shouldn't misinterpret my text message as an attempt to regain contact with her because I have moved on. I told her that she was just too superficial and vain for me and that for a woman her age, it's a disgrace.
Anyway, reflectively, she was quite too old for me, even though I am 28. I don't think I would have wanted to have a longterm relationship with her in the first place. Nonetheless, seeing her face again at the gym brought back so many painful memories and it reopened the wounds in my heart. I just did my best to ignore her. At one point, when I had to lift weights on a machine several feet away from the treadmill where she was running, she looked up at me and gave me this look as if she thought perhaps I was trying to approach her to confront her. I just ignored, her did my 34 reps and showed off my masculinity to great effect.
