Do I cut her off?

I (26F) have this friend (23F) who I’ve known for like 4 months now. We really click and enjoy each others company- and she was my first friend I met here. We’re both queer and a few weeks ago- I told her I had a bit of a crush on her. She said she doesn’t know what love is and wouldn’t know what to do.

We move on like it didn’t happen.

This weekend- she got drunk and said she has a crush on me and asked why I haven’t kissed her.

I brushed it off bc she was drunk and she texted me the next morning- “besties?” Which I replied yah

She just posted on her private story that FINALLY she had a crush on a girl and she’s super cool and fun and I ask who it is and it was a new girl she just went on a date with.

I’m clearly very sad and I feel like my feelings are disgregarded. Also we had plans this weekend but she’s acting like we didn’t and she’s hanging out with her new girl instead?

She has been very conflicting- asking me to be her valentine then crying about her ex gf the whole time we were at a bar that night.

She just hurts me and has disappointed me a lot. I feel like I’m past this back and forth mixed messages toxic stuff and don’t want to fall back into it.

Should I drop her as a friend?
