Search Results: wife of friend

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.
