Search Results: love confused

I have a girl friend, who I've known since around May. She has a boyfriend so I always looked at her as a friend.

Since December, she became very flirty. Lots of touching (massaging, playing with my hands, fixing my hair a lot, touching my neck, etc.) And sexual jokes (For example, I showed her a hoodie and asked her opinion on it, she said if she saw me in that she'd spit on it, then told me with a flirty smile that that's not the only thing she'd spit on, or I accidentally squeezed her neck too hard and I told her I don't know her neck that well yet and she asked "Well, you want to get to know my neck well?"). Or when she said something slightly mean I told her I'll punish her and she said she'd like it and I'm turning her on. And tons of other examples like this. She's also not bothered by the fact that people think we're together.

She told me I'm her last thought before sleep, I told her don't joke around and she said she's not joking (I still think she was joking haha). Or when she almost tripped she said "I almost fell on you" and I said "Well you already fell for me anyways so what does it matter" and she didn't deny it and smiled. Another similar situation to this when she said my coworker loves me (romantically) and I told her "She's not the only one" and she blushingly smiled.

So I'm kind of confused on what I should think. I'd like to think she's just joking around but she says and does these so often that I don't know anymore.
