Obligatory on mobile format apology. 

I was inspired by a similar post on this sub, but I think it's different enough to merit it's own post. 
I (19M) basically crushed on this girl (19F) from the first day of college. I felt comfortable around her, and I am generally very intraverted/socially awkward with newer people. We have become reasonably close (as friends of course) over the last year. I found out she had a boyfriend (reasonably long term from high school) and immediately made sure to put up a filter in our interactions. By this I mean that I made sure not to act overtly flirtacious with her/make a move, whatever you want to call it. I genuinely do value her friendship, and obviously if she were to become single later on, I would revisit the idea of pursuing a relationship with her. I do not want to be seen as TA because I have continued to be her friend even after knowing she has a bf, but I would ask her out in a heartbeat if she was single. 
AITA?
