It’s everything though, her appearance, her confidence, her lifestyle, her kids, her popularity, her job, its an all consuming envy, which can drive how we view interactions.
op, it’s fine to dislike each other, but you do need to understand what your jealousy is telling you. And it will impact how you interact with her, she will sense it.
is she bragging of is she just saying I am doing x or y. As simply talking about things is not bragging, as she has more than you. She doesn’t need to be quiet about it, so much depends on how she says things.
she’s popular, so it’s unlikely she’s that horrible. Was there more to not buying drinks for you, did you come in and biy your own for example and fhey were in rounds, did she owe her colleague one, was she being sensitive as it would have meant you’d feel like you should buy her one back and she’s aware you are in a different financial situation.there can be many reasons for someone’s behaviour but we can interpret it differently. Does she really let the door shut on you, or is she just rushing through and you’re far enough behind she doesn’t see you or waiting would be awkward. Again, many intepretetations to one act.
you don’t need to feel happy for her, she’s not your friend. I doubt she has that expectation on you.
are you comparing yourself, wanting what she’s got, to be popular, attractive, kids, the lifestyle, the job, then work out how to get there. Fix what your jealousy is telling you and use it to drive you forward. As otherwise right now, it’s jist hurting you,
