<human>: Summarize the given text in a few sentences.

So let me set the stage first:

I had just gotten out of my first relationship (also my first LTR(18 months)). It was a poisonous relationship with constant fighting on her part, and various other shitty things including a lackluster sex life and jealousy issues. However, the terms of the breakup were very shitty on my end. I cheated on her. I felt like complete scum and I hated myself for what I had done because I didn't know I was capable of doing such a thing. I grew extremely unhappy in the relationship, and looking back I think I may have been depressed, but I know that doesn't justify my actions. With the help of my close friends, I was able to come to terms with the situation and rationalize it in my mind. 

Now this is where things get sticky, so hold judgment and stay with me. The girl I cheated on with was a somewhat close friend, and somehow the event didn't sabotage our friendship. And after I worked up the nerve to break up with girl#1, we began to see eachother very regularly and quickly began dating. Things were just god damn amazing. This girl could melt my heart with the tiniest little smile, and she was always willing to do whatever I wanted to do (something I was not used to). After dating for a short period of time, I felt like I had known her for the longest time, and I felt extremely close to her. 

So now what's the point of all this you might ask yourself. After a month of dating, she has to move away with her family. We had agreed that we would not try a long distance relationship and that we would keep in close contact. Somehow in the short time we had together, I got really strong feelings for her and now I'm just in a shitty place. The rational side of me keeps saying "what happens happens. If it's meant to be, it'll happen eventually". And then the hopeless romantic, but still realistic side is saying "Maybe it really is meant to be. These feelings don't come from nowhere."

I'm sure there's some of you out there that have gone through something similar, so I'd just like to know what you did and how it worked for you.
<bot>: This girl I fell in love with in a short amount of time had to move away. How do I stay positive? Or should I even BE positive? Would it save me some heartache if I just moved on?
