To cut a long story short, I had arranged a date the first weekend of lockdown 1, it never went ahead but we continued to message each other anyway.
We were both in a similar situation. All of our friends are settled down, most have kids and we were the only single ones, so I think we possibly relied too much on each other considering we didn't know each other.
When the restrictions lifted, we managed to go on a few dates, but then we both had to isolate and the new lockdown came in. We have been Facetiming and calling each other, as well as a few walks.
I like his company and feel comfortable with him. He is funny and interesting. I sometimes think I'd like to kiss him, but I also feel like I'd need some dutch courage to do it 
He suggested that he makes dinner for Valentine's Day today and I suddenly just panicked. I want to do the decent thing and I don't want to lead him on, but I don't know what I want. I've never done anything, even kissed anyone, and it seems worse because it's been so long and I feel I've misled him. I don't know if I'm attracted to him.
