<human>: Can you condense the text into three sentences or less?

I started going out with (let's call her "C") nearly 4 years ago. We met through mutual friends, and all was going amazingly, until, for some reason, I broke up with C. I can't remember what my reasons were, but no doubt it was some immature, ridiculous reason. A year later, we're still friends (as we had the same circle of friends), but I started having feelings for her again. 

I didn't want to act on them, because I was afraid that I would only end up hurting her again, so I ignored them, even though I knew that she still had feelings for me too. Another year down the line, and these feelings got stronger than ever, and I knew I had to have her back, but by this time she had moved on, and was completely distant from me. Now for two years I've found myself completely mad for her, and she's got to the point where she has blocked me from all sorts of communication from her. I still have incredibly strong feelings for her, and no matter how much I try to get into any sort of relationship with someone, it never works, because they will never live up to her. 

Is there any hope of getting C back? Although I'm still young, I'm single for 3 years now, and I fear that she's the one that got away.
<bot>: I can't get over an ex who I broke up with, who seems to have cut off all communication between us, and I'm still mad about her.
