Got to know this coworker via another coworker/friend on a trip. Went on a group trip twice before she moved to the city and we started hanging out just a little more. A few months in, she then asked "would you be my boyfriend" in front of all her friends and she would repeatedly (sometimes but not always) reference me as her boyfriend when we are texting or during a conversation. However, she sometimes also say we are travel besties or besties while taking selfies together when hanging out 1-1.
In recent months, I've started to hang out with her a lot more, especially 1-1, and I would flirt with her very often and she would tease me back. I am 100% sure she knows I like her - we would share a bed on a group trip (nothing happened obviously), make inferences during a conversation that I like her etc...
Getting real mixed signals on this and I do plan on just asking her out and see but just want to get a pulse check first
She's also recently asked if i have a crush in general (while saying she has a couple), how i would propose...
