<human>: Can you condense the text into a few key points?

My girlfriend and I (both 19) have been in a relationship for only 9 months and everything was amazing up until the last month or so. Ever since the first days of the relationship she has been attached to me like none other; wanting to be together literally all of the time.
 At first I was very happy about this and I loved to spend time with her. But within the last month or so I have become annoyed by her routine calls wanting to spend every full day together. Along with this annoyance I am starting to become disgusted with her little habits that I once thought were cute, such as talking in a baby voice.
 I've been thinking a lot about this recently and I have tried weighing out the pros/cons of ending the relationship or just taking some space from her. One problem is that she has spent lot of time with my social circle and sometimes she even hangs out separately with a few of them and I am very anxious about what kind of awkwardness this might cause.
 What do you think, Reddit?
<bot>: Girlfriend is becoming annoying and she has made good friends in my social circle. What should I do to ask for space or end the relationship while trying to avoid as much awkwardness/tension as possible?
