Help with a Scorpio girl

I met her 2 weeks ago, she went to my place, common friend invited her. My friend knew I had a crush on this scorpio girl so she kept giving hints to the group, asking me to pass the drink to her, or get SG something. At fist, I was just laughing and just trying to coolly shrug off my friends teasing. Eventually, I got a bit buzzed by drinking, so I started making them all laugh, and went out of my way to make sure SG knew I had a crush on her, I kept glancing at her and stuff. It came to a point wherein the whole group would talk about how she should give me a chance, they said I was funny and I knew how to cook (I cooked for them when they came), and that I was thoughtful for hosting a last minute drinking sesh. They wound up asking about my ex from the same office we work in, they even searched her through FB. I saw her like whisper or mumble to her friend next to her to show her what my ex looked like. And then that friend said, "Hey, you look just like her!!!" Then we all just laughed cause it was true, but she's prettier 😊 And they said I had a "type", but I know I don't, it's just a coincidence. The night ended with her semi-hugging me before she left and thanking me for a fun night.

Sooo, I see her at the office sometimes. We smoke outside, sometimes just the 2 of us, sometimes with our friends. But we never talk about meeting up or something. We had another drinking sesh a week after. She brought her boyfriend with her (yeah, she has a bf. She got broken up with by someone else last Feb 2018, and she started seeing this new dude around April I think. It obvs looks like a rebound, even my friend thinks so). Anyway, she kept looking at me the whole time. I tried my best to ignore her. I just kept cracking jokes with everyone and was a bit of a life of the party, and she was sitting in front if me, next to her bf, and she kept laughing so loudly at my jokes but I just went on without looking at her so much whenever I was being funny.

And so at the office just this afternoon, I dunno, our friend kind of pushed her to me cause a car was gonna pass so we had to like get near the wall to make room. I was facing them, they were facing me, and our friend pushed her to me. I just tensed up and I can literally feel her breasts on me. I was surprised she didn't tense up, she even placed her arm on my shoulder. I didn't know what to do anymore so I was trying to think of something funny to say but they were already laughing. She remained so chill the whole time and I don't know what to think of it. She's a Scorpio, I'm a Cancer. Our friends know I like her, and I think she knows I like her cause of the way I kept joking about it with everyone. Even my friends who were there at the party kind of sensed that she was also giving signals that she was fond of me, to put it very lightly.

I just don't know how to approach this woman. I've had one scorpio ex, but this one's much closer to my age. I get the vibe she's game. But she has a bf. But she talks more about her ex than her bf so I don't know. What do you guys think? I'm so sorry this was a long post. Thank you in advance to whoever reads it all. 😊
