First time I met this girl we were having dinner with people from my dorm (I knew all of them). I was sitting next to her and we talked pretty much during the entire dinner. One thing I noticed was that she was speaking very closely to me (she approached me), almost whispering throughout the entire conversation and laughing at unfunny jokes I made.

When we headed back to our dorm all of us decided to head for the games room, there she started talking centimeters from my face again and practically invites me to her room. Thing is.. I had an exam the next day, and basically rejected her request.

In the days that followed during breakfast she would always sit next or in front of me. 4 days after our first encounter I decided to text her asking how an assignment she had went, she responded by telling that it was okay and asked me if I was doing anything "fun" that night. I responded: With your company I am, let's have dinner? She did not respond.

I only got a text from her the next day during the afternoon, and I suspect she only did so because I was talking to a few girls in our dorm's Whatsapp. I ignored her text and continued texting in the WhatsApp group. She eventually double texts asking me to bring her to an event that both of us were going to, I rejected her because I had plans.

At the event we were with different people but she suddenly approaches me, taps my shoulder and just walks away. I barely had time to say "hi", so I continued flirting with other women (I don't think she saw this).

Today at breakfast, for the first time, she purposely did not sit with me. Later during the afternoon I texted her asking if she was doing something tonight, she replied hours later saying maybe, I decided to push it once again and tell her the pub I was at. She responded with a "I'm tired" response, apparently she was at a musical with a friend.

I suspect that I should have asked her out personally, but at the time I just wasn't with her. I think there is plenty of bilateral attraction, but that both of us are playing a power game that isn't benefitting neither of us. Should I ghost?
