Hoping the bubble doesn’t burst

Our first date in January was great. We got on like a house on fire. I left thinking I'd made a new friend. Until he kissed me after our second date in March. I hadn't expected it. I hadn't expected it to be so amazing either.
What next?
I didn't have to think about that due to a little pandemic taking away any choices.
We've texted most days. Chatted on video calls for hours on end. He sings to me. We laugh. A lot. 
Uh oh. I realised I liked him more than I had ever intended to. I don't "date". I have mutually beneficial arrangements. I was hoping he would become that.
Neither of us had a support bubble and had been so safe and vigilant. We tentatively made plans to meet again. 
I wasn't nervous, just very excited to see him for our socially distanced garden meet. 
It turned into a scene from a film. I thought human touch after so long would be emotional and feel weird but the only thing that was weird was that it wasn't weird. It felt right.
The next time was even better. So easy. 
I've never been more real with any man and although I feel vulnerable, I feel safe. 
Whatever happens, I am so grateful to have been on this rollercoaster ride with him. 
He very well may have taught me how to let someone in and love again.
I have spent 11 years protecting myself from getting hurt and now here I am petrified that I'm falling for someone who may not be falling for me.
