<human>: I am new to this sub and don't really post on reddit but I am so lost right now I do not know what to do. Backstory, me and my girlfriend have been dating for a year and 4 months now. We have previously talked on and off but it did not work out for various reasons. Once we started dating though things have been amazing, we almost never fight and when we do we would cool off and talk it out. 

However the past couple days she has been accusing me and questioning me on if I really love her or if I have ever cheated on her. I have not and would never and I love her dearly. I thought things were going back to normal until she came over about 3 hours ago and looked upset. She would not say what it was, but I could tell something was bothering her. She finally admitted that she has been thinking and she has not been happy with life and does not know what to do and wants to take a break to see what she actually wants in life. She repeated that I am nothing but nice to her and does not want to lose me but she is at a point where she needs to step back from everything to reevaluate what she wants.

I am not sure what to do or how to win her over because I do not want to lose her but any input would help.

Provide a brief overview of the text.
<bot>: Me and my girlfriend are now on a break, she's confused, I am even more confused. Is there anything I can do to prevent a breakup?
