<human>: Can you give me a shortened version of the text?

I work with her, and just over a month back she started talking to me over Facebook. We would talk and flirt back and forth. Eventually I asked her for her number because fb messenger is a pain to use.

This is where it starts to get weird. She tells me that ever since I started tlaking to her on fb she can't get me out of here head. Asks me if I have feelings for her and what they might be. (Physical, If I would date her, or if I wanted to be friends) Told her given the opportunity I'd date her.

A day passes. She starts telling me that she wishes she was in a relationship with me and not her current bf. I tell her that I can't be the guy that ruins the relationship they have (he's a nice guy) so I slow conversation for a bit, changing the subject whenever anything comes up about it. 

I hang out with her a few times. Go to dinner, hang out at her place watching netflix. End up staying over a couple times (nothing happens besides a bit of cuddling at first) Stayed over again last night because she watched my puppy and lost track of time. Wasn't expecting it but she kissed me and because I have feelings for her, I kiss her back.

All while this is going on she has been sending me risqué texts behind her boyfriends back. I feel really uneasy about the whole thing. I would like to date her but I don't want her to break up with the guy for me. (they have been dating for 5 months) I'm not sure what I should do. Tell her she needs to make a decision and leave her to do so? Or just move on and forget about this girl.
<bot>: I have feelings for this girl. She has the same feelings but has a boyfriend. Not sure how to handle it.
