<human>: Summarize the given text in a few sentences.

Me and my girlfriend have been a pretty close couple for the past 5 months, we would always talk and have something interesting to talk about. 

However, recently she has been really distant in replying and during phone calls. She would usually ring me as well but not really focus on the conversation, often leading to awkward silences. Eventually she hung up on me. So after all this distance, I thought I'd finally go out on a limb and ask her if everything was alright. She said it was fine, but I asked if she was positive and that's when she got annoyed.

Of course she never told me that she was annoyed, until I got it out of her, and she said I annoyed her by asking if she was okay and if there was a reason she was distant. 

I sucked up my pride and apologised from the bottom of my heart. She then replies "that's all you can do for now, but I think I just need space for myself, I'll probably contact you soon, later". I replied by saying i hope we can discuss this as a mature couple but ill give you your space. She didn't reply.

Also literally two days ago she called me saying how much she missed me and how she cannot wait to see me (I study in another city, but live in the same city as her generally).

She's always made sure she let's me know how her day went etc usually. And she's shown me to her family and we get on.

I really don't know what to make of this.
<bot>: Girlfriend abruptly asked for space after a little misunderstanding, although she was so happy with the relationship two days ago.... any help what she could possibly mean? Breakup or actual space?
