<human>: Can you succinctly summarize the text in 1-3 sentences?

Ok. So to start, I am a 20 y.o. male and my girlfriend of 10 months is 20. 

We first met through mutual friends at university, and eventually I asked her out and she accepted (she had just come off of a relationship a few months before and was finally over her ex.) She has said multiple times she is afraid of getting hurt again, to which I assured her I would try my best not to hurt her.

The first couple of months were good, I hadnt developed too strong of feelings for her. But then she told me about 2-3 months after we were dating that she loved me. Now I wasnt even close to saying I loved her, but stupid me, I decided to say it back. 

Life went on, and we would hang out a lot, and I met her family and some of her extended family. However, I found out eventually  that I really didnt have much in common with her, and that I didnt love her, and could not see myself with her for the rest of my life. My mistake here was that I didnt end it then. She is totally in love with me now.

She is kind of immature and doesnt really act her age, and is overall not really someone I can relate to. After putting a lot of thought into it these past months, I have realized I need to end it before it gets too far and more painful. I need to end this relationship. But christmas is almost here, as is new years, and I cannot bear to ruin her holidays. Not to mention she has anxiety, and a few other medical issues that Im afraid will worsen just through me ending our relationship. 

I truly dread doing this break up, as I think she will be absolutely devastated, utterly destroyed. But it must be done. And she lives an hour from me, so I do not know how or where to do this. I am so conflicted but I know I cannot stay in a relationship I do not feel is right.
<bot>: I need to end my relationship with the girl who loves me, because I do not feel the same way and I do not want to hurt her even though it has to be done.
