Search Results: meeting new guys

I've known this girl for 2 years since starting university, a simple description would be a gleeful -- odd but outgoing -- focused person aspiring to go to medical school. Me on the other hand, A former anxiety-ridden guy who likes molecular genetics, top of the class but my social life does not exist (2 hour cummute to uni everday).

I saw just another uni friend, yet, I think through her being occasionally with my vicinity (e. g. at meeting events or elsewhere) we both got to know each other on a casual friends level. I knew she was getting comfortable around me; conversations ranged from random mundane stuff to deeper family issues on both sides. I began thinking "maybe, just maybe this person is a tad bit interested in me".

She had invited me to a Korean restaurant with 2 other uni friends we both knew (a homosexual and a guy already with a girlfriend, both similar age). Due to uni work, she cancelled -- which was understandable.

She calls out of the blue and we have plans to go to so the movie "Glass". in short, we were going alone together but I stupidly invite another friend who's 30 and the day involved me not really engaging much (it sucked). We both could tell she was uncomfortable and her excuse to not see the movie after we ate were because she could tell that I was tired and pretty much not enjoying this (which was true). life goes on.

She agrees to go to another restaurant with me (I initiated) and because I have slowly lost interest I cancel this a day before with the excuse -- I have a meeting (that I had no intentions of going to).

The next day I sit next to her in a lounge and things are normal, she had new earrings and dress and the conversation is fine albeit she seems to always try and get me talking despite me not initiating at all.

The signs?
Responds quickly whenever I text
gives me the same nicknames she calls her girlfriends
very touchy during conversations
Leaning in when we talk?
asks me what I think of the things she wears.

I’m with this girl for a year now, and 80% of the time far away.
I learned she’s having recent solo dates with a guy she met less than one month ago, in her own house, even though she says he’s just a friend. She says she’s free to be in a relationship and can join or leave whenever each other wants, that I can’t control her, not my prisoner, etc.
Every time I’m asking something about this subject she got crazy at the beginning, but now totally ignores me, says I’m crazy, on other hand says she only wants me, nobody else, that she can talk to whoever she wants.
As for me I got more controlling because I got to know about this new intensive friendship. And of course, insecurities started to rise because she lied to me. She has been hiding all this information about meetings this guy. She doesn’t even tell me who he is and what type of relationship has with him etc
Do I need any more hints?
