<human>: Background : We've known of each other for almost 2 years because of school (same major), but only recently got to know each other when she got hired at the place I work and I trained her. Now we're friendly, we talk at work, started sitting and working together in classes, but I now have a major crush on her. I'm not exactly an outgoing guy, but from the moment we started getting to know each other I can't seem to stop talking when I'm around her.

On to the problem: I have pretty low self confidence.  The only real relationship I've had lasted 3 years and ended when she cheated on me. This girl is also way out of my league.  She is very fit and attractive. Me, not so much.

On a good note, my crush has motivated me to start working out (I've gone on the treadmill every day for almost 2 weeks straight).

Not really sure what to do in this situation. The options I see are

A. Ignore the feelings, enjoy being friends.

B. Act on the feelings now, risk being rejected and losing the friendship. 

C. Wait til I shed some weight and gain some self confidence,  then act.

Can you condense the text into three sentences or less?
<bot>: Crushing on girl, don't want to fuck up friendship, but do what to see if the feeling is mutual.
