Good female co-worker friend I like now avoiding me?

Me and my female co-worker have known each other for about a year now. We use to be cubicle buddies but when I got promoted and moved a to a different section that's when I saw us getting closer. For example, she would come visit me everyday during her break or lunch and just sit and talk to each other this went on for three months and we would even go out for lunch together in my truck. It was a great and this is where I truly developed some feelings for her. However, I never said anything because well she has a boyfriend. We would sometimes catch each others glance and stare at each other even when I had a court date she felt very worried and would message me to good luck and she even told me she cared a lot about me. This has all changed within 3 weeks. Her boyfriends cousin now works with us. She slowly no longer would visit me at my desk for break or lunch which I understand but now it seems that is really going out of the way to avoid me. She always knew I liked her when she would visit me I never told her anything, but it was pretty obvious I did. She's very short with me on chat, or the HI's are a force smile and not as energetic as before. So I've started ignoring her back but it really hurts me to loose a good friend I've asked her if I have done anything to offend or if she was mad at me for a reason. She said no not to worry about it but I do because she seems to talk to everyone at work, say Hi, chat, be friend joke around with other people but me. I really do miss talking to her and have tried on several occasoins but I feel like I'm just bother her. When we leave for the day I would always usually walk her to her car and give her a kiss on the cheek or a hug goodbye and now when we walk out together she was walking ahead of me in a faster pace so there good be a void between us and we no longer hug or kiss on the cheek goodbye. Not sure why she would ignore me? Any advise?

other day a friend of mine told me she's been talking less to me because I was getting to attached to her which is what she told him. This was this two weeks ago. I was hurt by this because I did consider her a friend, anyways after this I began to ignore her completely no Hi's or hellos simply work related. She asked me what was wrong with me and if I was mad at her? I told her no pretty much. What I don't get is why does she care if I'm mad or not if she is avoiding me or not talking to me.
