Did a girl I fell in love with use me to make my friend jealous and to see if he liked her? And when they got it together why did she keep rubbing it in my face?

I would be very grateful if people to tell me what they think she was doing. Did I miss read her or was she using me? The problem is I want to move on but I’m still hurt in love with how I thought she was.

It all happened a few years ago, I had just moved to London to start a university course and was at the time recovering from major surgery, which left me with a colostomy. I was not looking fro a relationship as I was just starting to accept having a colostomy. When I started the course I met a lady how seem nice over time she started to be very tactile with me touching me and liked to sit next to me and she also laughed a lot at things I said. Slowly over time I fell in love with her, by this time she new of my medical condition. I decided to pluck up the courage to ask her out so I could tell her how I felt. I think she new I liked her as a mutual friend told me later on. She said she was having to do work on her dissertation o I thought ok, I tried this a couple of time and the same thing was said. The odd thing was if she wanted to be just friends I thought she would have gone out and told me she want to be just friends or stopped the tactile giggly behaver around me. I thought she was playing hard to get. Eventual she said yes but in the one of her voice it sounded like a plan had gone wrong, later that night accidentally her friend I was walking home drunkenly mentioned she like my now ex friend. He asked me a while before I f there was any women I liked and I said yes and told him, he said there was no one he liked. But strangely over time he started acting funny like sulking around me. I decided after hearing what the drunken friend said the best thing to do was to have no more contact with the girl I loved so I’d be able to concentrate on my course. This was fine she left me alone for awhile but then she started trying to sit next to me join in my conversation and giggling and the tactile behaviour, by this time she new I loved her and was hurt knowing how she felt about my friend. I soon realised she had started dating my friend how acted funny around me before and said he did not like anyone I think he did and she used me to make him jealous. By this time as they were together he was acting like and idiot and trying to be really friendly with me and she was acting flirty, the thing is I’d hated the fact the new I did not want to have anything to do with them but the seem to lovely telling me about the favourite places the went out like they mentioned they hand a favourite jazz bare noodle bar and had been to Venice. I want to get cross but we all share some friend so I didn’t. Strangely when she saw me at an event chatting to mystery girls she looked really pissed off then later on when I was alone on a different day looking at a gallery she accidentally was at with her boyfriend she seemed to poses no consideration to my feeling and ran up to me laughing and being tactile. Eventually I managed to get rid of her when the course finished as I left London. I would really appreciate if people could tell me what the think she was doing thank
