I accidentally agreed to someone wanting to be FWB with me

I wanted to get things off my mind today and I went to a straight bar smh cus my fav gay bar was closed today cus their vacation week. Anyways I randomly ranted to this woman about my personal life and issues, idk we both kept story timing till I randomly felt her hand on my hand thought of nothing till when asked if I wanted to be friends and I said yes and she asked me again cus it's friends with benefits and me being still dumb and a little drunk, I said yes thinking she means therapy friend and she invited me over to this hotel and oh THAT kind of friends. I'm literally on the bathroom rn typing this and idk what to do to get out of this situation
