Is this normal corporate workplace behavior, or am I 22F overthinking it?

I used to get along really well with a coworker when I first started my job. But over the last few months, after getting a few opportunities and more visibility at work, I feel like something has changed.

She’s been making little comments like “you’re so aggressive” or “wow, you’re making bank,” often in front of other coworkers. I’ve mostly ignored it, changed the subject, or just not engaged.

Recently, she told me she didn’t like the way I was doing a task. In the moment, I replied, “Do you want to do it or help me?” She said no.

Later, she sent a message in our department chat saying she didn’t like how this task was being done and that people were making excuses. No names mentioned, but it felt directed at me.

Now things are awkward. I said hi this morning and got a cold response, and it feels like she’s avoiding me.

This is my first corporate job, so I’m wondering: is this kind of thing normal? Should I try to clear the air, or just stay professional and move on?
