<human>: Give me the gist of the text in a nutshell

I am friends with a girl who I work with, and I have recently developed strong feelings for her. She's amazing, but I'm really not sure if she has any similar feelings. After spending an increasing amount of time alone together over the past few months, I feel like too much time has passed for me to still be wondering if she has feelings for me. I think we have a lot in common, and I've been told by others who I've sought advice from that she wouldn't be spending so much time with me if she didn't have similar feelings. At this point I've gotten no physical or verbal signals that would normally tip me off to go for it. I don't want to be confused about this any more, and it has come to a point where I'd rather her just know that I care a lot about her and want to be closer to her. 

I'm hesitant for a few different reasons. 1. We work together, with her in a position that is higher up than mine, and I don't want her to feel uncomfortable about that. 2. She's told me that she hasn't been in a relationship in a long time, and she feels comfortable being really picky about men at this point in her life because she's alright with being single and doesn't feel the need to seek out a relationship. This just totally messes with my confidence for obvious reasons. 

I'm not really sure how strong my feelings are and I don't even know if a relationship between us would work out, but I am just tired of being confused about things. So I'm seeking advice from you all on how to navigate this situation. I can't bring myself to say anything in person because it just never seems right. I've thought about writing her a letter or card and bringing it to her with flowers, but think maybe thats coming on too strong. I'm probably overthinking this, but I'd appreciate some fresh insight and maybe some tips from some women about how they like to be approached about this stuff.
<bot>: I've been hanging out with a girl who I've developed strong feelings for. Can't figure out if she feels the same, but I want to make my feelings known somehow, just not sure how.
