My good friend hates my happiness

Alright "hate" might be too strong of a word, but I just have this icky feeling in my stomach that my good friend doesn't like it when good things happen to me. She blatantly ignores any positive news I share, if I post an achievement she doesn't react to it. And I just had an amazing thing happen to me this weekend and I feel like she got upset when I told her. She ghosted me for a few days and now I feel like she's forcing herself to pretend she's ok but I can feel the bitterness, resentment and disappointment in her. I would cut her off but she's the one who has these episodes then comes back to retry our friendship. At this point I'm not reaching out. It feels like she's mad at me but I haven't done anything wrong. The happy things can be anything from doing well at work, to travel or her seeing me get something. My boyfriend surprised me with a trip I had wanted for a while this weekend. That's the reason she's not really talking to me now.
