Relationship potential? Show me the signs!

So, I intern with someone at a company that I think has shown some interest in me, and I really like her. I don’t know if she’s got a bf

Im really lost at reading signs, so I’d appreciate any advice to try and minimize making myself look like an idiot if I’m seeming wrong because we do interact in a professional environment, but I also can’t well describe everything here in this space

I’ll add my best girl friend thinks there’s definitely some level of interest

-We met at an after work event, and I just had a good feeling. We talked a lot, I made her laugh a lot. I left thinking wow I like this girl and I feel like she might to.

-She will come up and chat with me on occasion and seems interested in talking to me.

-She always seems very happy to see me, she smiles and definitely seems quite pleased to see me.

-We went on a small group lunch with her and that’s when I really started to sense things. She complimented my blazer. The waiter was quite funny and we’d look at each other. I made her laugh quite a bit. On the walk home we walked pretty close to me, we walked behind the rest of the group like 20 feet, and she unprovoked told me I should come visit her office and stuff like that.

-Then we went to an after work sporting event with all the interns. She came late and seemed super happy to see me, but I couldn’t talk right then. Later she came up to me and stood quite close when talking (we talked for 30+ min). I was getting her to laugh and she playfully touched my forearm with both hands and pushed my arm. Another time I noticed how close she was to me when asking a question. She also started to ask me some more personal stuff, like about how I’m recently out of a long term relationship (idk how she knew it was long term).

-I saw her the next in office work day in the elevator. Seemed very happy to see me and stood up more straight. We chatted, and got breakfast from our cafeteria. I was saying to her she’s bad luck because once she left the game, the team lost, and she gave me a little back handed tap on the bicep when I said it.

-Also, in our last two interactions, she’s also accidentally touched me 3-4 times. Once under the table at the restaurant, I think while adjusting her napkin, and then when we’re talking together I guess we stand quite close.

-I saw her once more yesterday in the cafe, she waved to me then we talked to each other for a minute.

-I’ll add that I don’t usually catch her staring at me and she doesn’t message me out of the blue or things like that

Personally I think in person it feels more convincing, but also wondering perspectives, and what about if she’s got a bf?
