Looking for serious answers - I'm really not sure!?

I met this woman aged 29 (I'm 24) through a friend at a party. 2nd time I met her I felt a strong connection between us. I think I'm having a bi curiousity towards (OK i KNOW I am) - for the first time for me. We are both known to be straight but there is something between us from the moment we met - I caught her looking at me across a room and looking away fast then back and we smiled. Well we got to talking, & she asked did I have a bf, which I dont...& I began flirting with her I remember, little things - playing with her hair in a friendly way, her knee whilst ping, looking at her lips.. At the end of the night she said I should come back to the friends house she was staying at... I couldnt...so I took her phone number. So I text her one night to say hey, how are you. She replied that she was in bed being eating a creme egg.... ;-) so I replied asking how does she eat it? ;-) & she said she bites off the top and licks out the goop...so I said wow u must have a strong tongue and she said yes i can savour one for at least 20 minutes. I was hoping she was flirting but now Im not sure. On another occasion she said "im giving men a break for now ;-)" when moaning about guys. Is this just straight girl talk or do u think she was flirting too please? thank u. She confused me after by flirting with guys infront of me in the bar then looking round at me, then having an on/off boyfriend. I honestly don't know if she is as girls are friendly with other girls all the time. thank u
