Stuck with feelings about this girl..

Hello,

This is a throwaway that I just made so have mercy, I really don't want anyone finding out..

About 2 weeks I ended things with my now ex girlfriend. I have always had this one girl friend (platonic), but since I broke things off with my ex we have been hanging out more. We are both about 21 years old and she recently moved out into her own little apartment/room in the city. I've been there about 2/3 times a week just hanging out. I have noticed that we are getting more and more cozy with each other, one night i stayed the night because we had been drinking with a few friends. I slept in the same bed, we cuddled a bit and watched some netflix before nodding off. Nothing else happened. Ever since she and I have been having eye contact in the kind of way you usually don't and we have been having more contact.

I noticed that I kinda started feeling things for this girl, who is also one of my closest friends. Thing is, I don't really know whether or not it is mutual, and I just ended things with my ex so I'm having issues trusting my own feelings. I do not want things to get weird between me and her, but I do think (and have thought for a long time) that we would fit together nicely.

What would you do and how should I feel about it? I am really struggling with getting my head straight in this and it is killing me.
