<human>: So without going into too much detail, we see each other every year when we go for holidays, we've really liked eachother for years now, but we never gave in because we live 600km away from each other. Last year we didn't meet for many reasons (I didn't go for holidays) and she got a boyfriend.

A few weeks ago we met again though and when we saw each other I pretended not to be interested, but all it took was a couple days, and we were hooked on each other....again. It really was a magical feeling. 

in those couple weeks we had many amazing nights on the beach and whatnot etc. 

And then the time came for us to leave, she now broke up with her boyfriend, and I feel mixed. I did it, I am together with the girl who I liked since forever, but she lives hundreds of km away from me, and It is because of me (they haven't been talking for 2 months prior though) :( 

She has been chatting with me ever since and I absolutely adore her still, but I am aware that LDR's are difficult. 

Her boyfriend knew about me, because he read her private messages to her best friend from 2 years ago (she was pissed) he sent me a message, explaining his side of the story, not important really just saying.

My dilemma is that I don't wanna mess it up.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Me and girl who liked eachother since forever but never did anything because of the distance, finally can't help it, she broke up with her old BF, now entering LDR, and am terrified.
