So this girl is actually a coworker of mine. When we first met we used to talk/joke around a lot, but honestly I didn’t have any feelings for her back then and just saw her as a coworker/friend. She used to mention her boyfriend every once in a while and it seems like their relationship is going just fine. It was like that for a year (she met her bf a little over a year ago too). But for the past few months I noticed that the tone has changed whenever we talk/interact. Sometimes she would indirectly flirt with me “as a joke” and give me other signs ( touching me, getting too close, laughing at all my jokes, eye contact, showing me pictures of herself in hot outfits). She doesn’t mention her boyfriend as much now. One time she got my number from another coworker and started texting me, even sending selfies. All her girl friends (even her best friend) at work treat the two of us like we’re dating, even though they know that she has a bf. Whenever we entered that phase (flirting) , that’s when I started having feelings for her, and now I don’t know what to do. Don’t get me wrong I respect her current relationship and don’t want to ruin anything, but I’d like some advice on how to handle this. Am I overthinking it and picking up the wrong “signs”? Should I ask her or her best friend about her relationship is going? Should I let her know how I feel? Should I play the long game and wait? Should I stop talking to her and drop the whole thing? I really like her now and don’t want to mess things up for anybody.
