Search Results: letting go of an ex

I was with my ex for 4 years, it was a high school relationship. I was heart broken after but we would just fight and i needed to venture. Anyway i moved to America - New York and met a gorgeous girl who just captivated me. I loved everything about her. I meet her a year after breaking up with my ex. We both dated from the get go, 4 months. I didn't want to make it official because i didn't want my ex to go psycho on this girl and also my work situation wasn't steady and i was likely moving in 1 months. Anyway, she stuck around. Another month went by but then she brought up what we were. I then told her that i got the job in Arizona and i think its best we break things off because long distance sucks and i didn't want heartbreak and to put a time frame on us. We we split. She felt lead on but wished me well. I believe someone then told my ex and all of a sudden she was heading to Arizona in 2 months to work there with friends. I move for work going nc with the newyork girl then my ex contacts me to go for drinks with her and her mates. I went more to give my ex closure. Im guessing the New York girl found out through photos my ex put on Facebook, next day im not her friend on Facebook anymore. I was instantly upset. Because she didn't tell me why. My number was also blocked. I then told my ex off and told her we need to stop and decided to take her and her family off my facebook. Its been 8 months now and i get word im heading back to new york for work. I contacted the girl by letting her best friend know on fb that im coming back. I then get an email a week later from the ny girl saying that she 'will always care about me' and she 'doesnt play games' and she 'doesnt want to make me jealous because its highschool crap'. However at the end of the email she put 'best wishes'. Which to me implies for me yo leave her alone. I want her back. I dont want to scare her awayIm at a crossroads. Which option should i take?

Sorry its so long, i guess im just in need of advice...
