<human>: Both her and I have been hired around the same time and through lucky coincidence in work times and small talk I have befriended her. Through talking she has indicated in our conversations that she has a boyfriend.

My dilemma now is what steps should I take? I feel I have 2 choices although please suggest any if you do have some.

1. Go after her and hope she will develop feelings for me and leave her boyfriend
2. Become a good friend and hope that she will choose you as her next boyfriend somewhere down the line

My concerns in choice 1 is that I will put her off and she will end up hating me and distancing herself. My concern for choice 2 is that I will friend-zone myself as I don't believe there is much I can do to keep the romantic/sexual interest between me and her high as she is currently in a relationship.

I do feel that I am much closer to her than any other male in our store. I do text and snapchat her a bit but not too much as i'm not that great at communicating via text. 

I just want to see her happy in the end because she is honestly the first girl in my life to make me feel this way. All other girls either used me or never even gave me their attention or efforts. She also is the first girl to have the most in common with me. But then again, if I keep playing the nice guy will I ever find a relationship at this rate?

I'm just praying that if I do go down the path of choice 1 that her relationship is already unsteady and I would not be the one to cause harm. 

Thanks a lot for listening guys, all inputs whether they be advice or personal experiences are helpful and much appreciated.

Could you distill the essence of the text into 1-3 sentences?
