Dating???

Please help me out here. I’m a shy person. I’m approached on the street multiple times a day so it’s not that I can’t “meet” people, I just don’t know how to get to know someone. I don’t know how to build friendships with intention of it evolving into something romantic. I don’t know how to build friendships in general. Just thinking about it makes me feel really awkward. Especially with it being winter time and Corona out there, how am I supposed to spend enough quality time with someone to get to know them? I have no idea what to say to people, what to talk about, what I should be asking them, etc.

I was with my ex for 3 years, since I was 17. I had relationships before him but that was high school, that’s different. I saw them everyday. How do I get to know NEW people? I’m friends with 1 person and I still don’t feel like I really know him at all.
