I can relate on a much smaller scale.
Coming out of highschool (2002) I was recruited by Ohio State, NotreDame, Harvard, Penn, Brown and Stanford for football. I 'SWORE' I was gonna marry my ex, so I stayed closer to home and went to a crappy school for a major I wasn't interested in. Well, a year later, she ended it for good and started dating/f@cking her HIGH SCHOOL english teacher. gross... anyways, I transferred and it was too late to play football. I was pretty tore up and lost a big opportunity.
BUT>... 3 years later, I'm here at the top of my class in Design @ Kent State. If I'd have been with her, i'd be an engineer somewhere, not enjoying my smalltown USA house we'd buy. Now I'm on track for whereever I'd like to live, and an NSX is in the plans. I'd NEVER be able to own that with her.
IT WILL GET BETTER. You sound like with the exception of being used by her, have had a pretty successful and good life so far..
just think how much better it can be without being held back by a jerk-off woman.
good luck to your future endeavors. oh, and miss miami, have any sisters in Ohio?
