Unusual behaviour from a female manager

I am a female who started working for a new company earlier this year. For the past six months, I have noticed unusual behaviour from my female manager (she chose me to work with her):

– I caught her eavesdropped on my conversation with another colleague after work

– refused to help me with an important task. I ended up having to seek assistance from others from another department

– each time I came up with new ideas, she will openly take them

– her constant focus on me while paying less attention to other employees whom I saw were doing personal activities during office hours

– I bought chocolates for the office, and later that day, she, too, bought chocolates for the office

I don’t understand why she is doing all these strange things. Can anybody explain her behaviour, please? Thanks in advance.

Here are what netizens think:

She sounds like a B who’s jealous of you. Wait till you meet one who imitates yr hairstyle, makeup and dressing anyway, keep yr ideas to yourself and share only when it’s for work and you have to, just work honestly and perhaps see if you need to find a new job if you can’t than.

She sees you as competition, someone who can supersede her. She probably concern you will eventually take her place

She is your long lost mother.

You think too much .. you pay attention on her and your other colleagues too much .. the saying If you don’t pay attention on her how you know she pay attention on you

no need to pay attention to insignificant people by including them in your daily thoughts. I don’t mean they’re not important but why bother to mess up our mental health if we can choose to ignore them and be happy, those people are harmless anyway..
