<human>: So I've worked with this woman off and on for 8 years and every year I just grow more and more fond of her. I want the relationship to be more but A:I'm overweight and B:I'm a college student that lives at home with his mom. I'm working on both, but I still have a year or more before I would be in a position where I feel like I would even have a chance. In the meantime, I still offer to buy or bring her lunch everyday and we text back and forth every so often. 

During most of the time I've known her, she has been involved with the father of her child, but it was only recently that they split up.

I guess I just want to know if I am setting myself up for failure or what. It kills me to have these feelings and to be able to do nothing about it.

Can you summarize the given text in a few sentences?
<bot>: I'm in love with a longtime co-worker but I don't have a shot. No idea how to shake those feelings.
