<human>: There is this girl is at my workplace(we're both 20) who I really like and has been for more than a year now. She has a boyfriend though, and has dated & lived with him for 2-3 years. Since I'm a part timer who goes to college and she works full time, I'm not as acquainted with as the other coworkers but we still talk and share laughs. My problem is that I keep having this shred of hope that she would like me and that maybe when things don't work out between her and her boyfriend, I can "go in for the kill". I've been obsessed about her almost everyday now and it's driving me crazy. I've lost sleep, dream about her (nothing sexual) and at one point lost my appetite. I would think about her all the time and wonder what she is doing. It hurts me and crushes my hope whenever I feel that we may have something going on, her boyfriend would come to work and they would kiss and hold hands. There's always this cycle of liking her and talking to her more because I believe that I'll be with her to not talking to her as much at work because I'll never be with her. I'm really at loss here as to what I should do. I'm not sure if we should just be friends because it always gives me this false hope. Please, wisemen (and wisewomen) of Reddit, give me guidance.
