<human>: First time posting, long time lurker, but I guess I need some help on something that has happened recently. It has been about a month since I met my girlfriend. For the sake of the argument, let's call her Amanda. A friend of mine hooked me up with Amanda, and since then, we have been going out. 

But there is a thing with Amanda. She never dated anyone else before. This is her first time in a relationship. I understand, since I was once first. During the month, she was actually quite playful and active, but as the time gone by, she began to be a bit childish. She began to call me names and began to treat me like I am like her girlfriend. First I thought, you know, this might be her way of getting closer to someone. But after the last date, I thought the teasing was going a bit too ridiculous to the point of thinking that I am not dating someone that has the same age as me, but rather I am dating some teenager.

At the end of the last date, I told her if she ever thinks about me when she teases or makes fun of me. She then goes quiet. I told her that although I really don't have anything against your playful nature, I want you to tune it down a little. She apologized and then told me that she had no intentions of making me feel bad or annoyed. She told me that a couple of friends have also told her  the same thing I said because she was acting like a boy in front of his crush. I kinda felt sorry for her, but I know that is really not the right way to show one's affection towards one another. 

I thought the whole thing was settled and we were going to have a relationship without the need for childishness. However, after that, she has been hastily answering my contacts, or just sending short messages. She does not seem really cheerful when I give her a text and I am worried if she (or I) am taking it way too seriously(or not). What should I do in this situation?

Summarize the given text in a few sentences.
<bot>: I asked my playful girlfriend to turn the teasing a slight notch down, but I am worried that she might have taken it the wrong way. What should I do?
