How did we get here? what's happening?

This woman has been interested in me for over a year. She communicated in several ways that she was interested in me, but I never paid her any mind. January 14, 2011 I finally respond to her and asked her out that night. She was nervous aswell as I. We double dated with my cousin and my best friend. We all had a great time and there was alot of chemistry between her and I. We talked constantly on the phone, getting to know eachother was very exciting. I made her feel good by simply being a good man, nothing more. She seemed extremely thankful for just the little things I've done, when I thought nothing of it and I would respond to her "this is what a man is suppose to do". She's been in a crappy marriage and apparently was a bit damaged. I told her that I'm a patient man. She wanted real and I gave it to her. I showed her compassion and appreciation. But happiness came and went. The relationship was going fast, we tried slowing down but our emotions and feelings for eachother was really getting the best of us. Then she started twisting my words and my actions. Simple things like leaving flowers or notes on her door step or calling her on a saturday morning to have breakfast, or askng her what her schedule looked like one week so that i can schedule time for us to spend together (since she communicated that i'm so busy with work) was my attempt to control her??? romance was no longer romance in this relationship and soon I was walking on eggshells with her. But I tried being patient with her, in my mind if I give her real and let her see that men are capable of love and sensativity that she will come around. in march she told me that she loved me so and wants to spend the rest of her life with me and that this scares her, she has never felt this way before....but things have been rocky. communication has been strained and often misinterpreted. I've been patient. we are now near the end of may. I feel like she and I have been together longer than 4 months. I've grown to love this woman, and I want to give this my best shot in making it work with her, but I'm starting to feel that she wants different. it's been almost two weeks. she hasnt shared how she felt about me at all. She doesnt want to talk to me, as it seems. I asked her several times "what's wrong?" but she would dismiss my question "nothing is wrong i'm fine, have a good day".....i try to reach out to her by giving her space and not talking to her all day, but send a small text saying "thinking of you and hoping you're doing well today" .... her response "thank you. have a nice day"......it's been a week and a half now and our convo's have been just like this. I call over the phone and I can tell she doesnt want to talk to me, it feels more so like i'm on the phone with a stranger...I can feel that something is wrong with her, but I seriously dont know what I did, nor why she is being so distant. she snapped on me on sunday when I tried talking to her, telling me to respect the fact that she has company (her friend) and STOP texting her, so i left her alone since.... I was advised to just let her be. cut her off. and see if she comes back or misses me. and if not then i have my answer all along. it's day two and I'm sick and I'm confused. I want and need answers. I don't understand HOW in the HEII i (we) got HERE. this relationship has been everything but smooth.... I dont know what to do. I don't want to push her away, so I left her be. but I don't want her to think that i don't care neither........ I know it's long and I am sorry.
