Search Results: signs a guy likes a girl

Try to think back to before you dated the last guy you went out with. Did you give him any signs that you liked him before dating him? What were your signs?

Just a short story for the gist of it: I've met this woman whom I greatly enjoy talking to, who is also very beautiful, extroverted, outgoing and social. We met at church and spoke on a few ocassions. When I talked to her she always looked me straight in the eyes without breaking away and all that. She mentioned a bit casually that she and her friends hosted regular get-togethers back at their campus and that I should come. I said I'd think about it, flash forward to the Sunday before the Tuesday for the get-together and without me saying anything she goes out of her way to ask me if her friend had added me to their whatsapp group, I say no and she does so personally immidiately *and* adds me to her personal whatsapp (even though she didn't need to). Now at the actual events where I've attended thrice now, she's been a bit more "distant" I suppose, not really initating convos, at times I think even avoiding eye contact. Last time though me, her and my sister who went along spoke and she mentioned that she "overheard" my conversation nearby with another guy when I talked about how "it could be a movie the way you met your wife", even though she was at that time in the midst of a high-pace card game, and she commented on hearing something about "romantic movies" (I nor he said nothing of romance at any point).

So am I being silly here, is it just "normal extroverted girl behavior" or is there something to gauge here in the form of romantic interest or attraction? Thankful for input. I feel like the invite and whatsapp deal could be a sign but I'm chronically cynical lol.
