Why is she avoiding me

Hi,

I’ve been friends with this girl for 5 months who has a boyfriend. She moved from the east coast out here in the West to be with him for his new job.

She doesn’t want to be with him, but doesn’t know how to end it because they live together. He is her first boyfriend. She is very shy, very innocent, and a good heart. He is very controlling and is busy working at a hedge fund and doesnt spend time at home wih her. Tells her what to eat and how she should dress. She told him that she doesnt feel the same way about him anymore and he begged her that he’s changed.

Our friendship morphed into a relationship and we realized that we are great for each other because we love each other’s imperfections. Even though I wanted to, I never forced her to break up because that needed to be her decision. She also told me that she loves me so much. A month ago, I told her I couldn’t keep seeing her for only 1hr every week because I wanted to be with her all the time. She cried and said her heart wants to be with me but she doesnt know why she cant leave this guy. Since that day she hasn’t responded to any of my friendly calls to see how she is doing. I also emailed her a letter stating that I didn’t think I would lose her as a friend .

The question is.. why is she avoiding me and did I do something wrong to a potential love of my life?
