For context, we're both women (bi) but I was the first woman she's ever slept with. We've been friends for 7 years but only recently became intimate. After sleeping together for the first time, we met up again at a piano performance. She nervously, without looking at me, reached over and held my hand. Then she started stroking my thigh. It was very intimate. After, we went back to her place and has sex again. We stared into each other's eyes for hours; it was the most romantic experience of my life. She asked me, while in bed, if I was ready to be in a serious relationship yet, and if I'd move to her city to be with. her.

Shortly after this occurred....SHE GHOSTED ME. Five months pass. Then, she comes back into my life saying she wants to be 'friends' over a voice note, and apologized for 'shutting down'.

Fast forward to just a few months ago: she invited me to go to a concert with her other friend, under the pretense that were were 'just friends' again. When her friend went to the bathroom she pushed. me against the wall and we just held each other. Then we were kissing. She whispered in my ear that she needed me to be "assertive and fight for her". Then, the next day when i asked her if she regretted what happened she said "maybe a little...I'm worried it set us back in our friendship." I'm livid.

Is this woman bisexual? Or was she just using me to experiment? She seemed so attracted to me when we were hooking up and there has always been sexual tension between us.

FYI: She's been 'straight' her whole life. And often says things like "but I'm not into woman" as a followup to aa very gay comment about a woman's body. There is extreme sexual tension between us, always.
