<human>: Give me a shortened version of the text

We met last year through a club at school.  We never really talked in-depth until the last couple of months before summer break, but we became good friends.  When we had the opportunity to take leadership positions in the organization, we decided to be co-leaders together.  A few weeks ago, we went on a leadership training trip that is supposed to help all of the co-leaders to get to know each other.  We got to spend a lot of time together, and ever since then I've developed a huge crush on her.  

I wouldn't hesitate to ask her out under almost any other circumstances.  Our interests line up even outside of the club's activities, and we're even from the same city.  The main "problem" that is keeping me from asking is the commitment we've made to the club as co-leaders.  We are expected to serve for two years, so if it doesn't work out between us I can't see any way to fulfill our roles as before without one of us dropping the activity altogether.  Neither of us wants to do that.  

To complicate matters further, she also dated my friend and roommate (M 19) for about a month last year before she ended it because she wasn't ready for a relationship at the time.  My friend has moved on since then and is currently seeing someone else. 

I think I'm too close to the situation to be able to make the best decision.  Should I man up and express my feelings to her, or should I try to move on and focus my attention somewhere else?  Thanks for any and all responses.
<bot>: I have a crush on a friend, but I'm afraid to make a move because of our shared commitments and (brief) dating history with a roommate.
