<human>: Can you condense the text into a few key points?

I've (M28) been FWB with a girl (24) for 6 months. We hang out every single day for hours, and basically are a couple without the official title. (We use pet names, we talk about each other's days, we go out to dinner, etc) A couple weeks ago I realized I really like her beyond just sex, so I told her. She told me she felt the same. Since then we've acted pretty much the same, except for me mentioning that I could fall in love with her/marry her one day. We never discussed being exclusive.

This past week I slept with a few different girls, so I didn't have much time for my FWB. I didn't talk to her for a few days which is very unusual, and when I did I mentioned sleeping with the girls, as I've always told her about my hookups. She usually responds with some supportive answer, but this time she said she felt disgusted and was done talking for the night. She's usually very chill and not the jealous type, so it was even weirder to experience that response from her. 

I asked her about it the next day, and she told me what I do with other girls is fine, and doesn't bother her, but rather telling her I liked her was the problem. She acknowledged that we aren't exclusive, and said she would've been fine continuing our friendship without all the "fake i like you stuff". I told her I do actually like her though, and my feelings aren't fake. She said that is hard to believe.

I haven't spoken to her in a couple of days, and I think she wants me to feel sorry, and I don't. I asked her to give me another chance and to wait for me until I felt ready for commitment. She said she wouldn't wait for me, as I hadn't.

I'm really confused why she is suddenly mad about my hookups when she has been fine with them before. Am I in the wrong here? Any advice would be appreciated, I don't know where to go from here.

Thanks!
<bot>: I (M28) slept with other women, and my FWB (F24) now wants nothing to do with me. What can I do about this?
