I want to start by thanking everyone who left a reply. I knew the question of ethics would be unavoidable, and of course we both should have been more aware of what we were doing and avoided the situation. I would be a liar if I said I wasn't happy that it happened in hindsight; I was vague about our relationship and how close we became as friends before our encounter. She leaned on me and I her; our encounter was definitely unexpected and in the moment. We were both very much in the moment, I couldn't say who initiated it.
I haven't stopped thinking about this for two weeks and I've gone over everything we've talked about. I realized I know a lot about her, and I'd like to know more. We talked yesterday and we talked about how we felt. It felt good to tell her and after a long talk we were both happy.
We're getting to know each other, and that's exactly what I wanted, to get to know her on a non occupational basis. And I was happy to know the feelings were mutual.

I have been referred to another therapist. My therapist told me she was doing it the day after our encounter and I had expected it. In that respect she was very professional and acted quickly. Thank you all for asking. I wasn't expecting so many replies, I'm truly grateful to you all and hope to return the support one day.
