How to respond to hints from bff

Hey, My best friend of 6 years has been dropping hints at me that she has feelings, which I reciprocate. The thing is she has been dropping them for like a month, and during that time a cocktail of emotions were happening inside me. First I wasn’t sure they were hints, then I wasn’t sure if I had feelings, I was then certain of both of these things when I had to travel for a while. A small recap, she would constantly lay her head on my shoulder , my chest. She was being way too flirty than normal telling me i’m handsome and one of the best looking guys. She was also overtly playing the “we’re friends” card whilst giving mixed signals which i immediately understood as her creating temptation through our taboo “breaking through the friendship into lovers” thing. Now being the dumb idiot i am, but also because i had placed her in my mind in a very specific non romantic place, it was very hard for me to get them. The biggest thing she did however was on the last day i saw her, she had full make up on, made her hair, beautifully dressed, and when we went for a walk she laid her head on me, grabbed my arm and started running her fingers up and down my arm. That’s when I was certain. The place where i think fucked up was when I was driving her and my friend back home, she tells me to drop my friend first and then her (even though her house is before his’). In retrospect of the situation, she was expecting a move from me which i didn’t do ( i just hugged her goodbye 😭).

But like now, how the hell do I make a move? she has been texting me more often even more than my guy friends. What is the level of directness I should aim for?
