<human>: Can you succinctly summarize the text in 1-3 sentences?

So I have just finished my second year of university and I have had a crush on this girl since very early on in first year. It took me a long time to finally get the guts to even talk to her, by which point she already had a boyfriend. We become pretty close over the next year or two, to the point where I consider her one of my best friends and vice versa there was about a month leading up to exams where we would hang out like everyday, and I start to fall for her more because she's just the best. She's still with the same guy throughout all of this time. 

In those two years a couple of our mutual friends admitted to her while they were drunk that they had crushes on her, which lead to her and I making a lot of jokes about how I was her only real platonic friend. This lead to me one night after spending most of the day with her telling her that I used to have a crush on her in first year but was now over her, she was a bit surprised at first but didn't take it too badly. We now laugh about it and make jokes about it (me more than her which as I am writing this now probably shows she might not like them).

I honestly thought I was over her, it's now summer break and apart from semi regular messages I don't see her anymore and am not so sure. She still has a boyfriend and, apart from one night drunkenly telling me they had been having some problems, they are very happy together. But even if she didn't I wouldn't want to lose her as a friend by getting in a relationship with her if it didn't work out. I guess my question is how do I deal with all of this? Do I have to stop being friends with her, as much as it would kill me, to truly get over her?
<bot>: I became super close friends with my crush, who has a boyfriend. I thought I got over her but don't think I am.
