Is my girlfriend’s friend into me or just playing around?

Anonymous
My girl has a coworker that has invited us twice to hang out and each time we have hung out we have gotten pretty drunk. I’m not much of a drinker so I try not to drink so much since I get drunk really fast. However, when we hang out with my girl’s coworker, it can be hard not to drink since her coworker is very wild/playful and always wants to get us drunk and party. She seems like the type of girl that flirts with everybody. The first time we hung out we went to a club. When we left my girl’s coworker began talking about having sex with the bar tender saying things like “I would let him put his penis in me” when it was just three of us in the car. I didn’t mind since I’ve noticed some girls get like that when they drink, but it’s odd since I don’t really know the girl and she’s talking like that when me and my girl are alone with her. The second and previous time we hung out was at a pool party. At one point me and my girlfriend were near the corner of the pool. I was close to the edge of the pool in my own personal space about 2-3 feet away from the corner of the pool. My girlfriend was in front of me in her own personal space about 4-5 feet to my front left also about 2 feet away from the corner. Her coworker then shows up to chat and takes the corner. There was enough room for all of us to be in our personal space and a gap in between me and my girlfriend in which you could swim by without bumping into each other. When my girl’s coworker came to chat she went through the gap without bumping into us, but when she left to leave the pool, she didn’t take the gap and walked closer to me, bumped into my foot and leg and playfully said to my girl that I tried to trip her. Not sure what that was all about but my girl asked me why I did that. I didn’t do it on purpose and I told her that. We were kinda drunk but just curious, is this girl into me? I don’t want to have an issue with my girlfriend but I feel like this girl might bring some issues.
