Wow, reading these broken heart stories has me thinking back 24 years to the time of the break-up with my last ex-girlfriend. My last girlfriend has been my wife for 23 years.
My ex-girlfriend was a smart tough feminazi. I grew up a lot that year, but most of it was painful. It ended when she came home and said she spent the afternoon "sleeping" with another guy. So, I packed my stuff and moved back to my place.
The first couple of weeks after that I was in agony and I was worthless; couldn't work much. Still had pain for months, but it faded over time. Until I met my future wife and all was well again.
Brianna, your time and mileage may vary, but things will get better for you too. There are better guys out there than the lying professor. It's his job to help you with university things. It's immoral to take advantage of someone in a vulnerable position.
My ex-girlfriend was from Philadelphia and was a big Flyers fan. Sorry folks, but to this day, I root against Philadelphia teams; living in Pittsburgh just added to that.
