Even I can't figure out my deal!

I am worried I have a raging crush on someone who has a girlfriend. Now, while this may seem inconsequential to some, to me it is actually a really big deal. Nothing will ever happen from it, but it is certainly a new thing for me to actually like someone who I know is already preoccupied.

I rarely delve into this territory and so, to me, it spurs more questions; I don't know the girl - never met her - is that the difference?, how can I possibly like someone who I know it would never work with (or is that why I like them?), do I just find them a distraction - what is a crush anyway?

Either way, it is starting to get onto my conscious a bit. In the few times we have hung out and actually talked with meaning I have found myself flirting with him (ok. to the extent that someone in my position can or does) and have found him mentioning his girlfriend on two separate occasions. While I might not be able to control my feelings I can certainly control my actions, and would never do anything...but it is weird to feel this way especially since someone in a relationship is extreme off-limits for me.

Perhaps just more testing of the boundaries I have created for myself?
