I don't know if likes me or just is being nice?

the other day i had some strong interactions with my coworker. a few times she came up to my area i was working to hang out. another time i was walking around on my own and she came up from behind me to walk next to me. two times we had strong eye contact, the first time it was as if she was wanting me to be next to her without making it obvious, but i could be wrong, second time we were pretty close and she was just staring off in the distance then our eyes eventually caught and that lasted a few seconds, but eventually she threw up the peace sign and that totally threw me off. she also called me bro in a separate convo which also threw me off. so i'm not sure where i stand, is she interested?
