So I met this girl in September which immediately struck me. She is a friend of a close (female) friend. We immediately got in contact reciprocally, as in we would both text each other and meet up basically every day (we study at the same faculty and she is a year ahead of me) and talk and have a good time. Little did I know she had a boyfriend at that time and that things were not going well for them.

I ignored the situation and kept on contacting her as much as she contacted me. After some time news were she was single and that night, with a bunch of friends, we all went clubbing. She and I danced basically together all night and she was onto kissing me but I refused given the circumstances (not wanted to hurry things). However in the car back home we cuddled, so i assume everything was cool about it.

Few days passed and we went out a night around uni, nothing too special. And I took that opportunity to clarify the situation of me not kissing her and to declare the obvious that I like her. She did the same but told me she was confused after the recent brake-up and I took it with great ease and calmness. Sunday (after a week from the club) I took her out and we made-out all night until I took her back home.

Monday, Tuesday and Wednesday we kind of escaped uni to go smooching in private and she used to be all like: I miss you when I am at home, I think about you and such.
Day after she said that she needed to sort out her prievious elationship as she still was confused and was getting overly involved sentimentally with me and did NOT want to use me to get over her ex, so we went on standby mode.
She kept texting me and I answered, I rarely wrote to her. Tuesday she said that I better move on for the time being as she doesn't feel like commiting right now and wants to be alone some time, I let her go.

Silly enough I asked a friend to find out what she was up to, and this friend got caught and she got really pissed off at me and called me on Sunday saying not to meddle in her business and that between me and everything is over (she was furious so I kind of let the whole phone call slip).

From that call onwards we have almost no contact a part from a hello when I see her and she sees me. She still is feeling uncomfortable around me as I gathered from a recent dinner we had with friends.

So now I find myself troubled. Was I a rebound? I don't think I was since she actually asked for a standby instead of keeping up the story. Do i have future chance with her? We really had it going when we flirted for a good month and she always kept saying how much she felt great with me and stuff.

I was thinking about giving some cool off time, let her sort herself and then maybe re-enter the scene from scratch and try and construct a solid relation.
What do you guys think?

P.S. Her boyfriend kept showing at her door and calling her when we were seeing each other and I had advice given me from our common friend during the time and I am afriad the thing slipped from her tongue and I came off as immature
