Am I overreacting?

What does it mean when a guy copies a girl?
What does it mean when a girl gets her hair locked and styled beautifully. The guy goes and gets locs.
What about if she got a tatto, he decides to go and get one.
What about if she went and got a dog. He decides to go get a dog.
What about if she decides to release something on a specific date. He decides to release the same thing on the specific date she had planned.
What does that mean? Because I don’t think it as flattering when a person does things as such.
Then turns around and wonder why I don’t share anything with them.
