I've been friends with Anne for 10 years now. We initially bonded over the fact that we both want to be musicians. While I've been actively working on it, she hasn't really done anything about it, she just vaguely says she wants to be a musician someday.

A few years after I met Anne, I went abroad to study. I kept in touch with her while I was away. One day, when we were talking on the phone, she just blurted this out: "I'm really jealous of you because you got to study abroad, and it makes it really hard for me to talk to you."

From then on, I never talked to her about studying abroad, or anything related, because I didn't want her to feel bad. We drifted apart, and though we still kept in touch, it wasn't the same as before. A few years later, she got the chance to study abroad, and turned it down because she was afraid of living on her own (she has always lived with her parents). I was really irritated by this after she said she was jealous, but didn't say anything.

Some time later she moved to a different country. A few months ago, there was a conference in our town for aspiring musicians. I casually mentioned it to her and she got really excited and told me I had to go. Once I got back, I gave Anne a brief summary of what I learned, because I was afraid she might be jealous of me for getting to go. (this conference is held every year and she could have gone before, but never went. She couldn't go this time as she had moved away).

Anne messaged me back, really excited, and asked me to give her all the details of what I learned, so I did. The way I see it, we both have the same passions and if our roles were reversed, I'd want to know everything she learned. I told her everything so that it was like she'd been there herself. She never replied. I waited, but after 2 weeks it became obvious she wasn't going to reply and I started thinking that maybe she was jealous about this too. Eventually I messaged her something really generic, I didn't say anything about the conference or the fact that she never replied, and she didn't mention it either.

Since then, we have drifted apart even more. Now all our communication is initiated by me. It was always like that, but after I started the conversation she usually kept it going like old times. But now, she just gives me some generic reply and doesn't bother to keep the conversation going. 

I don't really know what to do because I don't want to lose her as a friend. I don't understand how she can be jealous of me about things she also has the chance to do. I've had problems too, life and death problems, and she knows about those. I just don't understand her, because I've never been jealous of anyone. I want our friendship to go back to the way it was before, but I'm also not sure if I want to be friends with her if she feels negatively about me. How do I make sure I don't lose this friendship?
